Abstract:

Direct study of cometary nuclei which began 30 years ago shows the diversity of origin processes, the nature of cometary bodies, their comas and the areas of their origin. It may be noted that the frequent assertion that the study of physics and evolution of comets speed up the study of fundamental questions about the origin of the solar system, is a bit naive. On contrary, it reveals all the new processes that complicate our notion on the origin of the solar system. Comparison of the most detailed studied comets, as comets 1P/Halley and 67P/Churyumov-Gerasimenko, points to significant differences in their physical and chemical properties, dynamics and evolution. Researches of their properties and shapes showed that part of the cometary nucleus may be a result of low-speed collisions of planetesimals. The hypothesis of the origin of the cometary nucleus as a result of collisions of planetesimals has long been known, but it is 67P/CG comet that gave it relevance. The report shows that in some cases the geometry of the cometary nucleus retains some information about processes of collision and allows finding the momentum of the impactor.

Abstract:

Large scale vortices in protoplanetary disks are thought to form and survive long enough to significantly change the global disk evolution. They can capture and concentrate the dust particles embedded in the gas possibly explaining asymmetries and dust concentrations recently observed at submillimeter and millimeter wavelengths. The high-concentration regions formed by the vortices could be preferred sites of planet formation where agglomeration processes and gravitational instabilities could lead to primordial bodies like planetesimals or planetary embryos. I will first review the various possibilities to form robust vortices by the Rossby wave or the baroclinic instability in the case of non-stratified and stratified disks. Then, I will present the dust/vortex interaction and the trapping mechanism. Finally, I will discuss the evolution of the vortices once heavily loaded with dust particles and the possibility to form planetesimals.

Abstract:

Magnetic monopoles may catalyze nucleon decay (RC effect) according to the particle physics. Using the RC effect, we proposed a model of a super-massive star with magnetic monopoles at the Galactic Center (instead of the black hole model) 30 years ago and three predictions in our papers of ApJL in 2001 have been quantitatively confirmed recent years: 1) a strong radial magnetic field near the GC is confirmed by the observation in 2013; 2) The emitting rate of the positrons from the GC is consistence with the observation in 2003; and 3) The spectrum peak of the thermal radiation is at 1013 Hz in the sub-mm wavelength regime is consistence with the observation in 2013. These are the astronomical observational evidences of magnetic monopoles. Besides, we have estimated the number of magnetic monopoles interior of stars and planets, which were captured from the space since the star formation. Based on the estimation and taking the RC effect as the energy source, we propose an unified model of supernova driven by magnetic monopoles, which may simply explain the core collapsed supernova: SNII, SNIb, SNIc and SLSN and the dark explosion of SN very well.

Abstract:

The relativistic double neutron star binary PSR J0737-3039 shows clear evidences of orbital phase-dependent wind-companion interaction, both in radio and X-rays. In this work, we performed the timing analysis of 2006 and 2011 XMM-Newton large programs data. We detected pulsations from PSR J0737-3039A (PSR A) - with very high precision in measuring the spin period and PSR J07370-3039B (PSR B) despite its previous disappearance in radio. Interaction of PSR A's wind with PSR B's magnetosphere could have determinate the observed orbital pulsed flux and profile variations of PSR B as well as a loss of pulsar phase coherence on timescales of years. Evidence of orbital flux variability (∼7%) is observed for the first time, involving a bow-shock scenario between PSR A's wind and PSR B's magnetosphere.

Abstract:

The giant-impact hypothesis is the dominant theory as to how the Earth-Moon system was formed, but angular momentum concerns have cast a shadow on its validity. Computer generated impacts have been successful in producing virtual Earth-Moon systems that possess many of the properties of the observed system, but when tasked with addressing the isotopic similarities between the Earth and Moon they result in systems with excessive angular momentum. Evection resonance between the Moon and the Sun has been put forth as a means of removing the excess angular momentum, but this reasoning was rejected by the Royal Society at a special session called to discuss the origin of the Moon. Here we show how to use impactor spins to create an impact that preserves all the favorable aspects of previous simulations, and produces an Earth-Moon system with the correct angular momentum. Evection resonance is not needed. All the work is done on inexpensive NVIDIA GPUs, demonstrating how supercomputing and computational astrophysics has come to the masses.

Abstract:

Nearly a century ago, Edwin Hubble was among the first (including also Sir James Jeans) to notice a systematic trend of variation of galaxy properties along a morphological sequence, from highly flattened disky shapes to gradually more bulgy shapes, and onward to elliptical galaxies of varying ellipticity. It took the accumulation of observational evidence and the advance of theoretical understanding of the subsequent decades for us to learn that this morphological sequence, classified by Hubble in the eponymous Atlas edited by Sandage, was likely an evolutionary sequence, i.e., the so-called early-Hubble-types (bulgy or elliptical ones) are the results of the gradual central concentration of matter from the so-called late-Hubble-types (disky ones). Galaxies, thus evolve throughout the cosmic time along the (reverse) Hubble sequence from the late to the early Hubble types. In the past 25 years, the we have gradually established a dynamical framework, built on the foundation of the density wave theory of galaxies, which demonstrated how this so-called secular morphological evolution of galaxies along the Hubble sequence can be accomplished through the nonlinear and collective interaction of the galaxy-disk matter with the density-wave modes (these modes are the intrinsic global instabilities on the parent galaxy disks, and they give galaxies the striking appearance of grand-design spiral arms and bars). The analytical predictions have received extensive confirmation from observations and from N-body simulations. The result of this work has important implications on the cosmological evolution of galaxies.

Abstract:

Mars’s weak electromagnetic field (E/M) is the reason why it has been losing its atmosphere/oxygen much faster than earth, observed by NASA study. Therefore, the first step for planet-flipping requires cosmos reconstructive engineering of its thin atmosphere (hostile to lives), which can be accomplished by growing its electromagnetic field. Such said approach isn’t a theory, it is a fact. The world’s electric production has almost tripled in the last century. Along with earth’s inherited motion, the electrification of our home planet has increased its E/M field, which causes global re-climate/gas retaining or warming. It is evidenced by the tremendous increase of the Earth’s lightning strikes and storms/clouds in the past twenty years. The E/M force follows Newton's third law, which is clearly supported by experiment as well. To utilize its force in cosmos, the author develops your budget trip and economic lodge/landing system with “aerospace stellar sail and electromagnetic topography establishment” or Asset E©â„—. Asset Eâ„— will be the cosmos version of an affordable commercial airline and utility company. The Asset Eâ„— can be easily modified for asteroid mining/diverting and man-made flying objects (harmful) recycling. The code of cosmos conduct is expected to be an extension of earth’s practice. To ensure our home planet’s safety, I will discuss the necessity for globalizing a medical/humanitarian code-a version of 5150 in California, along with its physics for enforcing it.

Abstract:

We study analytically and numerically the dynamics and interaction of vortex structures in the continuum, and, specifically, in fluids and plasmas in two-dimensional approximation, when the Euler-type equations are applicable for modeling of vortex motion of inviscid fluid and guiding-center plasma. For numerical simulation we used the modified contour dynamic (CD) method. We fulfilled a number of the series of numerical simulations for study of two-vortex interaction, the interaction in the N-vortex systems, including interaction between the vortex structures and the dust particles, and also interaction of three-dimensional plane-rotating vortex structures within the framework of many-layer model of medium. We investigated the applications of the results obtained from dynamics of the vortex structures in the atmosphere, hydrosphere and plasma, for example: the problem of dynamics of evolution of the cyclonic type synoptic and ocean vortices which can be considered as a vorticity front, and also interaction in the vortex-dust particles system, and the dynamics of charged filaments which represent streams of charged particles in a uniform magnetic field in 2D model of plasma of Taylor-McNamara. The results obtained showed that for all cases in dependence on initial conditions two regimes of the interaction can be observed, namely: weak interaction with quasi-stationary evolution and active interaction with the "phase intermixing", when the evolution can lead to formation of complex forms of vorticity regions. The theoretical explanation of the effects, which we observed, is given on the basis of the generalized critical parameter introduced which determines qualitative character of interaction of vortices.

Abstract:

Transmission of TV images is a commonly used modern method in both space research of celestial bodies and the search for extraterrestrial life in the Solar system. In 1982, experiments in television photography instrumented by the Soviet VENERA-13 and VENERA-14 landers, returned panoramas of the Venus surface at the landing site. Over the past 34 years, no similar missions have been sent to Venus by any space agency, mainly due to the reason that the experiments were of extreme technical complexity. The archive data of the television experiment were reprocessed, which significantly improved the image definition quality. Analysis of treated VENERA panoramic images revealed objects that might indicate the presence of hypothetical forms of Venusian flora and fauna. Among them is ‘amisada’ that stands out with an unusual shape against the stone plates surrounding it. The ‘amisada’ can be included into the list of the most interesting findings of the hypothetical Venusian fauna. 'Stems' objects possess apparent terramorphic features of Earth-like floras. Among hypothetical flora entities of Venus, certain unusual findings that have similar structure were found in different areas of the planet. Their shape was repeated on various panoramas that were taken by different landers' cameras and have attracted researcher’s attention. Along with unknown forms, objects were found whose shapes resembled certain living forms of Earth. This phenomenon, i.e., similarity to Earth’s fauna and flora, was called terramorphism.

Abstract:

During the last years TeV emission has been detected from Pulsar wind nebulae. A new model by now has been developed explaining part of this emission by a hadronic component which consequently also predicts TeV neutrino emission. As galactic sources, many of the PWN are in direct view of the Antares neutrino telescope which can with its excellent angular resolution for several of the sources probe the emission, also considering the morphology of the sources. We use the IceCube non detection to put constraints on the fraction of TeV photons that might be contributed by hadrons and estimate the number of neutrino events that can be expected from these sources.

Abstract:

The search for life in the Universe is the fundamental topic of exobiology. The aim of my presentation is to comment on Galactic aspects as well as to explore which types of stars provide environments most consistent with exolife. Besides the sizes of the stellar habitable zones, we will also discuss the potential impact of energetic radiation (i.e., EUV and X-rays) on habitability. Finally, we will study the possibility of exolife for planets in multiple stellar systems, noting that in any of those systems the orbital stability of planets as well as the radiative environments deserves careful considerations.

Abstract:

The comparatively large value of the neutrino mixing angle θ₁₃ measured in 2012 by neutrino reactor experiments has opened the possibility to observe for the first time CP violation in the leptonic sector. The measured value of θ₁₃ also privileges the 2^nd oscillation maximum for the discovery of CP violation instead of the usually used 1^st oscillation maximum. The sensitivity at the 2^nd oscillation maximum is about three times higher than at the 1^st oscillation maximum implying a significantly lower sensitivity to systematic errors. Measuring at the 2^nd oscillation maximum necessitates a very intense neutrino beam with the appropriate energy. The world’s most intense pulsed spallation neutron source, the European Spallation Source, has a proton linac with 5 MW power and 2 GeV energy. This linac also has the potential to become the proton driver of the world’s most intense neutrino beam with very high potential for the discovery of neutrino CP violation. The physics performance of that neutrino super beam in conjunction with a megaton water Cherenkov neutrino detector installed ca. 1000 m down in a mine at a distance of about 500 km from ESS has been evaluated. In addition, the use of such a detector will make it possible to extent the physics program to proton-decay, atmospheric neutrinos and astrophysics searches. The ESS proton linac upgrade, the accumulator ring needed for proton pulse compression, the target station optimization and the physics potential are described. In addition to the production of neutrinos, this facility will also be a copious source of muons which could be used to feed a low energy nuSTORM facility, a future neutrino factory or a muon collider. The ESS linac, under construction, will reach full operation at 5 MW by 2023 after which the upgrades for the neutrino facility could start.

Abstract:

The relativistic effects in electrons and ions particularly during magnetic storms and solar fluxes in outer and inner radiation belts, magnetospheric regions affect the linear behavior of the plasma modes faced by space probes/missions of any kind by the world community. Recently observed characteristic changes in space probes due to the presence of the charged dust particles and quantum effects in certain domain of wave phenomena are some additional causing factors of complexity. The fascinating well behaved nonlinear structure – ‘solitary waves’ found in space plasmas engulfing interplanetary regions are an interesting area of research. The regions of existence of these structures with variable pressures occurring usually in space subject to relativistic and quantum effects in plasmas/dusty plasmas under well-defined conditions may be helpful to deal with these complexities. Due to inclusion of relativistic effects in plasma particles, the usual condition for the formation of nonlinear solitary waves in warm plasmas necessitates to redefine or modify some entity. Our model: investigation of inertia of electrons demands an unusual result   because in usual plasma modes, isothermal ions are to satisfy and adiabatic electrons to satisfy i.e for high temperature T_e. This inspires us to redefine C_s with relativistic effects which admit the feasible condition . In the second attempt of multi component dusty plasmas with quantum effects in the inertia less electrons, we have established a special method through a differential equation to deduce the ‘energy integral’ (which is usually not possible in general) to show the existence of the nonlinear solitary waves. A new quantum parameter C₂ with defined range connecting the quantum term of the plasma wave equation is unearthed to predict the existence of solitary waves in dusty plasma.

Abstract:

The scintillation detectors (SDs) based on organic plastic scintillators (OPS) are one of the basic detectors in HEP experiments. The technologies of OPS production as bars (strips) and tiles, their optical and physical properties, light collection based on wavelength shifting (WLS) fibers coupled to multi-pixel vacuum and silicon PMs are presented. SDs are multifunctional i.e. calorimeters, triggers, tracking, time-of-flight and veto-systems are examples of their field of applications. The use of SDs in many HEP experiments on the searching for quarks, new particles and H-bosons (D0, ATLAS and CMS), quark-gluon plasma (ALICE), CP-violation (LHCb and KLOE), ν-oscillation (MINOS and OPERA), and cosmic particles (AMS-2) are discussed. SDs still holds great promise for future HEP experiments due to such properties as high segmentation, WLS fiber light collection and multi-pixel silicon PMs.

Abstract:

This paper describes how to use gene expression programming (GEP) as an evolutionary computational optimization approach. GEP, as a machine learning technique is usually used for modeling physical phenomena by discovering a new function. In case of modeling the p–p interactions at large hadrons collider (LHC) experiments, GEP is used to simulate and predict the total cross-section, as a function of total center-of-mass from low to high energy √s, Considering the discovered function, trained on experimental data of particle data group shows a good match as compared with the other models. The predicted values of total cross section at √s = 8, 10 and 14 TeV are found to be 10, 105 and 111 mb, respectively. Moreover, those predicted values are in good agreement with those reported by Nakamura, Cudell and Block.

Abstract:

An accreting supermassive blackhole, the central engine of active galactic nucleus (AGN), is capable of exciting extreme amplitude Alfven waves whose wavelength (wave packet) size is characterized by its clumpiness. The ponderomotive force is driven by these Alfven waves propagating along the AGN (blazar) jet, and is capable of accelerating protons/nuclei to extreme energies beyond Zetta-electron volt (ZeV =10²¹ eV). Such acceleration is prompt, localized, and does not suffer from the multiple scattering/bending enveloped in the Fermi acceleration that causes excessive synchrotron radiation loss beyond 10¹⁹ eV. The ponderomotive accerelation was confirmed one-dimentional particle-in-cell simulations. The production rate of ZeV cosmic rays is found to be consistent with the observed gamma-ray luminosity function of blazars and their time variabilities, while the episodic phase of the acceleration and the spectral index may be explainable by the present theory. General relativisitic Magneto-hydrodynamics simulations show the intermittent eruptions of electro-magnetic waves from the innermost region of the accretiond disk around a black hole.

Abstract:

We present some results that have been obtained in previous works regarding the large-N pion scattering phenomenology at both zero and finite temperature. This is fully attained when working with an O(N+1)/O(N) non-linear sigma model (NLSM) in the chiral limit (i.e., a large number of N massless pions) as an approach for low-energy QCD, and after introducing a thermal bath via the imaginary time formalism. At zero temperature, we fit the parameters of the NLSM to obtain an accurate description of the scattering data in the scalar channel and in this way, dynamically generate the f₀(500) resonance, whose pole position (mass and decay width) is in good accordance with experimental determinations. After building up the pion scattering amplitude at non-zero temperature, we check that thermal unitarity holds exactly; thanks to this, we study the behavior with temperature of the resonance mentioned before and see how it is related with chiral symmetry restoration when a physical observable such as the scalar susceptibility is saturated by the f₀(500) state. In this last case, we obtain a second-order phase transition result, something that is in accordance with lattice and theoretical analysis. Besides this, we find that the critical exponent associated with the susceptibility lies within the range expected for a four-dimensional O(N) universality class. Finally, we show some insights of our newest research interests, also related with phase transitions and QCD critical phenomena in this framework.

Abstract:

We derive here a relatively simple expression for the total wind mass loss rates in QSOs within the accretion disk wind scenario. We show that the simple expression derived here for QSO disk wind mass loss rate is in very good agreement with the more “exact” values obtained through significantly more complex and detailed numerically intensive 2.5D time-dependent simulations. Additionally we show that for typical QSO parameters, the disk itself will be emitting mostly in the UV/optical spectrum, in turn implying that the X-ray emission from QSOs likely is produced through some physical mechanism acting at radii smaller than the inner disk radius (for a standard accretion disk, half of the initially gravitational potential energy of the accreting disk mass is emitted directly by the disk, while the other half “falls” closer towards the black hole than the inner disk radius). We also show that for typical QSO parameters, the disk itself is dominated by continuum radiation pressure (rather than thermal pressure), resulting in a “flat disk” (except for the innermost disk regions)

Abstract:

The LHCb collaboration has reported deviations from the standard model (SM) in b → s`<sup>+</sup>`⁻ decays. These can be explained within U(1)⁰ gauge extensions of the SM, in which the corresponding Z⁰ gauge boson can mediate b → s`<sup>+</sup>`⁻ transitions at tree level. In these models SM fermions carry family-dependent U(1)⁰ charges in order to generate the required flavor changing Z⁰ to quarks and lepton non-universality. We showed that such models can also accommodate a dark sector and the dark matter candidates can annihilate efficiently to produce the observed relic density. A big class of models to explain the flavor anomalies contains hypothetical particle leptoquarks. We correlate such models to the s-channel enhancement of neutrino-quark scattering in the very high energy shower events observed by the IceCube collaboration.

Gilbert Leon Joseph Beaudry started his present journey of unraveling the secrets of the Universe on February 4, 2004.  In January 2007, a descry observation in technology and latter in nature revealed a relationship between the requirements of observation and energy as being the missing piece of the puzzle needed to unlock many presently confusing unsolved mysteries of the Universe. The subject of his presentation on the recognition of energy spectrum observations beyond the thermal spectrum will allow for new theoretical developments with revolutionary changing clarity that will open up a new Universe. He presently blogs and promotes open science with public collaboration at PhysicsOfUniverse.com and as Astrophysics Research Channel on Google+ and YouTube.

Abstract:

It has been challenging to explain all the abnormalities seen in the processing of electromagnetic spectrum information from the Universe which is providing concepts, models, and explanations that produces controversies in many circles. It’s also generally agreed by the scientific community that there is a substantial lack of solid empirical evidence to support much of the ideals and speculations provided. Mysteries and abnormalities sometimes exist because of wrong reasoning that cannot resolve many problems. However, sometimes historically a new technology and/or a keen observation of a phenomenon swings a door wide open to create a scientific revolution with a fundamental shift, that gives us a clearer understanding of our Universe. The solid state physics of how the light emitting band-gap energy of a light emitting diode (LED) produces specific electromagnetic spectrum frequencies is a visual demonstration of a real relationship between energy levels and frequencies observed. Understanding the results from a LED laboratory experiment, combined with creditable scientific methodologies, and reasoning from natural occurring phenomena provide the missing keys to eliminate many abnormalities and problems, and to solve cosmic mysteries from the present mysterious universe. The phenomenon to be recognized in this science presentation is the recognition of the dualism of the electromagnetic spectrum. The dualism is, there exists not only the observation of thermal radiation as described by Planck’s black-body radiation, but also the mathematical induction observation of energy radiation, that radiates beyond the physical realm of thermal radiation. That energy radiation is observed in the Universe, to be quantized.

Abstract:

Query on Accelerating Expansion of the Universe I: We have found some serious faults in error analysis of SNIa observations, which led to the idea of accelerating expansion of the Universe. Redoing the same error analysis of SNIa, by our idea, it is found that the average total observational error of SNIa is obviously greater than 0.55^m, so we can’t decide whether the universe is accelerating expansion or not.

Query on Accelerating Expansion of the Universe II: Besides, we will discuss a possible reason of the departure from isotropy of the observed cosmic microwave background temperature.

Abstract:

Study of nonlinear wave structures of soliton and vortex types in complex continuous media (including space plasma, atmosphere and hydrosphere) is the important direction of modern nonlinear physics having numerous important applications. Such structures of various types can be observed in the Earth atmosphere and hydrosphere, in plasma of ionosphere and magnetosphere, as dust vortices on surfaces of the Earth and Mars, as dust sound solitons on the Moon, etc. At construction of dynamic models of continuous media the analytical and numerical methods of study of the equations of hydrodynamics and plasma physics are used. This allows considering numerous dynamical effects in real physical media, including thin dispersive ones, dissipation and instabilities of various type. Changes of media parameters are quite often accompanied by the bifurcation phenomena, such as a tornado and hurricanes in an atmosphere, shock waves and vortices in a plasma, etc. Association of efforts of researchers of nonlinear wave structures in complex continuous media and an exchange of opinions between them are rather important for the further development of this research area and can provide rather essential synergetic effect.

Abstract:

Theoretically and numerically the generation and evolution of solitary IGW and TID at the front of the solar terminator for conditions close to real ones in the F-layer of the ionosphere was studied. In particular it is shown that under certain conditions in the morning and in the evening, sectors of the solar terminator front can generate the soliton-like "precursors" with periods of order 40-60 min. The results of the measurements of total electron content (TEC) at two spatial-separated experimental sites during the solar terminator passage in the evening hours are presented in this report. Parameters of TEC variations were obtained by dual frequency global navigation satellite systems (GNSS) diagnostics. Obtained good qualitative agreements between the theoretical and numerical modeling results are presented. At present, the fact of generation of the TID under the influence of the ionosphere by powerful radio emission of "Sura" facility is experimentally proved. In this case, the TID may travel over long distance (up to 1000 km) along and across the magnetic field lines of the Earth, but as it is well known, the development of artificial ionospheric irregularities including the large-scale irregularities in the field of powerful radio waves occurs along the geomagnetic field lines, i.e. along the geomagnetic longitude. However, the results of the experiments, obtained on network of GNSS-receivers situated at spatially separated sites along the geomagnetic latitude: Vasilsursk (56â—¦08′N, 46â—¦05′ E), Zelenodolsk (55â—¦52′N, 48â—¦33′E) and Kazan (55â—¦48′N, 49â—¦08′E), presented in this report allow to speak about development of large-scale ionospheric irregularities stimulated by powerful radio waves of “Sura” facility that can propagate along the geomagnetic latitude, i.e. across the magnetic field lines of the Earth. One possible mechanism to explain this phenomenon may be the one that is described below. In it shown that within the “Sura” facility main lobe a region of reduced electron density is formed, while outside this region the electron density is increased. Thereby, a sharp gradient of the electron density is formed on the border of the main lobe of “Sura” facility that may cause the generation of a solitary wave, as is discussed in. In this case, a solitary wave of the charged component of ionosphere may cause the generation of IGW that in turn can cause the formation of a TID. As it is well known, non-linear solitary waves can propagate over significant distances under certain conditions, and the Earth’s magnetic field does not affect the propagation of IGW.

Abstract:

Near Earth space (ionosphere, magnetosphere) is characterized by complicated dynamics and for modeling of such processes, especially at conditions of external non-stationary impact (bow shock), it is very important for estimation of determined and stochastic parts of the dynamics, as well as the possibility of the generation of large scale wave and fractal structures. In this work, a physical model of the plasma perturbations for experimental data treatment and their physical and theoretical interpretation is obtained. In this model, a nonlinear mechanism of interaction of the perturbations with spatially inhomogeneous space flows is considered. Numerical simulation of formation of such large scale flows are carried out. Time series of velocity flow and magnetic field components of the magnetospheric flows observed by THEMIS satellite mission are studied by virtue of nonlinear methods. For numerical treatment of these data a recurrent diagram method is used, which is effective for short data series. Recurrence is a fundamental feature of the dissipative dynamical systems, which is used for analysis of relaxation processes in the magnetotail. The results of nonlinear analysis of plasma perturbations for interpretation are compared with the signals obtained by Lorentz and Weierstrass function. By virtue of recurrent diagram method, a fractal nature of experimental signals and dynamical chaos parameters. The results of satellite and numerical simulation data are compared.

Abstract:

In February 2016, the LIGO Scientific Collaboration and Virgo Collaboration reported the detection of gravitational waves produced from the inspiral and merger of two stellar mass black holes. In addition to being the first direct measurement of a gravitational wave by an earth-based detector, this is the first observation of a coalescing binary black hole system, the first evidence that “heavy” stellar mass black holes exist, and the first test of general relativity in the strong-field regime. Successively, in June the LIGO and Virgo Collaborations announced that the same instruments have caught a second robust signal from two black holes in their final orbits and then their coalescence into a single black hole. With these two confirmed detections, along with a third likely detection made in October 2015 (believed also to be caused by a pair of merging black holes) we can now start to estimate the rate of black hole coalescences in the Universe based not on theory, but on real observations.

Abstract:

A summary will be given of various approaches that can be used for doing numerical Hartree-Fock and many-body calculations on atoms and molecules. The theoretical approaches considered include the multi-configuration Hartree-Fock method and many-body perturbation theory. For light atoms and molecules, more than 98 percent of the correlation energy is due to pair excitations. Because molecules lack spherical symmetry, Schrodinger-like equations for molecules typically involve many more independent variables. While, the Hartree-Fock equations for atoms involve a single radial variable and the two-electron pair equation for atoms involve two radial variables, the Hartree-Fock equations for diatomic molecules involves two independent variables and the pair equation for diatomic molecules involve independent variables. To deal with these problems of higher-dimensionality, my mathematical collaborators and I have developed numerical methods for dividing the variable space into smaller sub-regions in which the equations can be solved independently. This domain de-composition theory is described and numerical results are given for Hartree-Fock calculations for diatomic molecules and for numerical solutions of the first-order pair equations which can be used to evaluate the Goldstone diagrams that arise in many-body calculations of molecular spectra. The goal of our calculations is to describe the energy of two helium atoms approaching each other in a cold atomic collision and to obtain the spectral fingerprints of CO and OH molecules in planetary atmospheres.

Abstract:

An M6.5-class flare was observed at N12E56 on the solar surface at 16:06 U on July 8, 2014. In association with the flare, two neutron detectors located at high mountain locations, Mt. Sierra Negra in Mexico and Mt. Chacaltaya in Bolivia, recorded two neutron pulses, separated approximately by 30 min. Moreover, enhancements were also observed by the solar neutron detector onboard the International Space Station. We analyzed these data and contrasted them with solar images from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory. From the existing evidence, we noticed that the production mechanism of neutrons cannot be explained by a single model; at least one of the enhancements can be explained by an electric field generated by the collision of magnetic loops and the other by the shock acceleration mechanism at the front side of the CME.

Abstract:

Three of the important puzzles in cosmology relate to the origin of baryon asymmetry in the Universe, the nature of dark matter and the cosmic coincidence that the amount of dark matter and visible matter are comparable. In this talk, I will discuss about the classes of models where baryon asymmetry and dark matter have a common origin within the framework of U extensions of the standard model and of the minimal supersymmetric standard model. In one model all of the fundamental interactions do not violate lepton number, and the total B-L in the Universe vanishes, which is quite different from previous mechanisms that baryon or lepton number are violated in generating the matter and anti-matter asymmetry. In addition, one may also generate a normal hierarchy of neutrino masses and mixings in conformity with the current data from Daya Bay reactor neutrino experiment.

Abstract:

We compute the series of thermodynamic quantities such as local temperature, heat capacity and free energy of Bardeen black hole to explore its thermodynamic properties that subject to the horizon and charge of this kind of black hole. For the sufficiently high temperature, the black hole with large horizon radius survives. Only tiny black holes and huge ones have positive heat capacity, which lead to stable black holes. We also discuss the thermodynamic characteristics associated with the charge to check the existence and stability of the Bardeen black hole. The black holes involving the large charge can remain stable; although their sizes are not extremely small or extremely large. The influence from the charge of Bardeen black hole on its critical temperature, heat capacity and free energy is obvious and distinct. There may be more black holes with magnetic charge than in the case of vanishing charge within a region of local temperature. If the local temperature becomes high enough, only large black holes will emerge, no matter whether they have magnetic charge or not. The black holes without magnetic charge cannot exist stably unless they are huge.

Abstract:

The classical Kepler problem gives a very good description of planetary motion, but is not realistic when the distance approaches zero (because the velocity becomes unbounded), and does not extend to the motion of massless particles (even though light is deflected by gravity). We show that it is possible to extend the Kepler problem by defining a new Hamiltonian for the problem where the velocity is always less than the velocity of light c, and even goes to zero when approaching collision; and also the motion of massless particles can be realistically described since it obeys Fermat's principle of least time. At the same time, Kepler's three famous laws governing planetary motion are equally well accounted. We then describe some non-classical properties of the motion, such as the existence of a new type of hyperbolic motion, which we call super-hyperbolic motion, characterized by a velocity that is always increasing with the distance (contrary to classical hyperbolic motion, whose velocity is always decreasing ), and which corresponds to the motion of very high energy objects. As it turns out, the gravitational action is repulsive in this case as well as in the case of collision and near-collisions motions. And most remarkably, the motion of massless particles is always repulsive. Finally, we indicate briefly how this generalization of the Kepler problem can be extended to the N-Body problem where, as before, the velocities are always bounded, and the motion of massless particles can be realistically described.

Abstract:

The angular distributions of doubly charged fragments of a nucleus ¹⁶О with the momentum 4.5А GeV c^-1 and ²⁰⁸Pb with the momentum 160А GeV c^-1 during their interaction with photoemulsion nuclei were studied. Contrary to common belief that fragmentation of relativistic nuclei in a wide range of masses and energy conforms to the statistical model, the experimental angular distributions of doubly charged fragments of these nuclei are not described by this model. The mechanisms of fragmentation of the oxygen nuclei can at least be assumed based on angle measurements and visual observation of all events of their inelastic interactions with emulsion nuclei. The lead nuclei fragmentation is associated with much more numerous processes. But it is not possible to identify them using the angular measurements only.

Abstract:

Loop quantum gravity predicts that the area is quantized as the area operator only admits discrete eigenvalues. In 1996, Rovelli suggested a connection between the black hole entropy and the area spectrum; the number of ways in which the area of the black hole horizon can be expressed as the sum of the unit areas (i.e. area eigenvalues) is the black hole degeneracy. In this talk, I will calculate the black hole degeneracy (i.e. the exponential of black hole entropy) by using Rovelli’s idea. However, it is now widely believed in loop quantum grvity community that Rovelli’s picture of black hole entropy is not the complete answer, as one has to further impose an extra condition. The word “naive” in the naive black hole degeneracy means that this extra condition is not considered; I only use Rovelli’s idea. However, it may be possible that the naive black hole degeneracy is the real black hole degeneracy (i.e. that we do not need to take the extra condition) as I showed in another paper of mine with Brian Kong.

Abstract:

The COMPASS experiment at CERN is one of the leading experiments studying the nucleon spin structure. These studies are being carried on since 2002, by measuring hadrons produced in deep inelastic scattering (DIS) of 160 GeV/c and 200 GeV/c polarized muons off different polarized targets. One of the main goals is to determine how the total longitudinal spin projection of the nucleon, 1/2, is distributed among its constituents, quarks and gluons. Regarding this topic the latest results from COMPASS on the quark and gluon helicity will be shown. Another major goal, whose fulfillment is needed for a complete understanding of the nucleon structure, is the determination of the transverse momentum dependent parton distributions (TMDs). An overview of the TMD results from semi-inclusive DIS will also be presented. In 2015 COMPASS scattered a negative pion beam of 190 GeV/c off a transversely polarized proton target, with the goal of accessing the TMDs of both hadrons without any prior knowledge on fragmentation functions. This was the first ever polarized Drell-Yan (DY) experiment with a pion beam. Since the DY data covers part of the DIS kinematic region, COMPASS has the unique opportunity to test the sign change of the Sivers TMD as predicted by QCD. This is a crucial test to the formalism of non-perturbative QCD. Preliminary results will be shown. Finally, the COMPASS plan to measure generalized parton distributions (GPDs) is also discussed. The first GPD run was taken in 2016.

Abstract:

Deformations of the focusing non-linear Schrodinger model (NLS) are considered in the context of the Quasi-integrability concept. We strengthen the results of JHEP09 (2012) 103 for bright soliton collisions. We addressed the focusing NLS as a complement to the one in JHEP03(2016)005, in which the modified defocusing NLS models with dark solitons were shown to exhibit an infinite tower of exactly conserved charges. We show, by means of analytical and numerical methods, that for certain two-bright-soliton solutions, in which the modulus and phase of the complex modified NLS field exhibit even parities under a space-reflection symmetry, the first four and the sequence of even order charges are exactly conserved during the scattering process of the solitons. We perform extensive numerical simulations and consider the bright solitons with deformed potential. However, for two-soliton field components without definite parity we also show numerically the vanishing of the first non-trivial anomaly and the exact conservation of the relevant charge. So, the parity symmetry seems to be a sufficient but not a necessary condition for the existence of the infinite tower of conserved charges. The model supports elastic scattering of solitons for a wide range of values of the amplitudes and parameters. Since the NLS equation is ubiquitous, our results may find potential applications in several areas of non-linear science.

Abstract:

One of the criticisms of general relativity is that it does not explain the concept of inertia. Mach’s principle stated that the inertia of a body is somehow due to the presence of other bodies in the universe. If this is true, then it is most especially relevant to formulate an understanding of space, and its causal relation to matter. In this regard, we propose that introduction of biological models appertaining to space, quantum theory and relativity may be prerequisite for understanding the connection of space and matter, photons and phonons. A new particle-wave equation, mc²=BvLq, formulates the conceptual framework for inertial electromagnetic induction (IEMI), perhaps representing the initial physical mechanism for non-ionizing radiation (NIR) bio effects. Derived from standard formulae, a new insight is introduced to provide an innovative, physiologic and efficacious approach to magneto-therapy. Specific experimental reports are cited wherein the modeling and EMF parameters were dictated by theory. It is hypothesized that Jacobson Resonance Theory is the missing link that Einstein sought for unifying the fundamental forces of nature: the electromagnetic, gravitational and nuclear forces.

Abstract:

Carbon deposition, as the main cause of supported Ni catalysts in CH₄/CO₂ reforming, is sensitive to the metal Ni particle size. To explore what’s the reason of the particle size effect during the catalysis process, Ni clusters, Ni₄, Ni₈ and Ni₁₂ which reflect the different cluster thicknesses supported on the MgO (100) slabs, have been adapted to simulate Ni/MgO catalysts. By using density functional theory (DFT), the reaction pathways of CH₄/CO₂ reforming on Nix/MgO (100) models are used to investigate the particle size that might affect the reaction pathway. The reforming mechanisms of CH₄/CO₂ on different Nix/MgO (100) indicate the energy barriers of CH₄ dissociated adsorption, CH dissociation and C oxidation three factors are all declining with the decrease of the Ni cluster size. The Hirshfeld charges analyses of those three steps show only atoms of Nix cluster on bottom or second bottom layer can obtain electrons from the MgO supporter and the main electrons transferring are occurring between adsorbed species and the Ni atoms in surface layer. The Ni atoms of surface layer in small Ni cluster will have more electrons and have better catalytic activity. As a result, the NiO/MgO catalysts with small Ni particle would expose more Ni atoms in contact with the MgO supporter, which might be the reason of metal particle size effect.
