The Origin of the Multiwavelength Emission of PKS 0502+049
N. Sahakyan
The origin of the multiwavelength emission from PKS 0502+049 neighboring the first cosmic neutrino source TXS 0506+056 is studied using the data observed by Fermi-LAT and Swift UVO…
Time evolution of rotating and magnetized white dwarf stars
Laura Becerra, Kuantay Boshkayev, Jorge. A. Rueda +1
We investigate the evolution of isolated, zero and finite temperature, massive, uniformly rotating and highly magnetized white dwarf stars under angular momentum loss driven by mag…
On the GeV emission of the type I BdHN GRB 130427A
R. Ruffini, R. Moradi, J. A. Rueda +9
We propose that the "inner engine" of a type I binary-driven hypernova (BdHN) is composed of a Kerr black hole (BH) in a non-stationary state, embedded in a uniform magnetic field…
The Powerful Jet and Gamma-Ray Flare of the Quasar PKS 0438436
Brian Punsly, Andrea Tramacere, Preeti Kharb +1
PKS 0438436 at a redshift of has been previously recognized as possessing perhaps the most luminous known synchrotron jet. Little is known about this source since the…
BKL oscillations in 2+1 space-time dimensions
Philipp Fleig, Vladimir A. Belinski
We investigate the question whether there are cosmological models in 2+1 space-time dimensions which exhibit dynamics similar to BKL oscillations, as the cosmological singularity i…
Two Predictions of supernova: GRB 130427A / SN 2013cq and GRB 180728A / SN 2018fip
Yu Wang, Jorge A. Rueda, Remo Ruffini +4
On 2018 July 28, GRB 180728A triggered \textit{Swift} satellites and, soon after the determination of the redshift, we identified this source as a type II binary-driven hypernova (…
Probing Lorentz violation effects via a laser beam interacting with a high-energy charged lepton beam
Seddigheh Tizchang, Rohoollah Mohammadi, She-Sheng Xue
In this work, the conversion of linear polarization of a laser beam to circular one through its forward scattering by a TeV order charged lepton beam in the presence of Lorentz vio…
Revealing the Broad Line Region of NGC 1275: The Relationship to Jet Power
Brian Punsly, Paola Marziani, Vardha N. Bennert +2
NGC 1275 is one of the most conspicuous active galactic nuclei (AGN) in the local Universe. The radio jet currently emits a flux density of Jy at mm wavelengths,…
Supercluster A2142 and collapse in action - infalling and merging groups and galaxy transformations
Maret Einasto, Mirt Gramann, Changbom Park +8
We study the dynamical state and properties of galaxies and groups in the supercluster SClA2142 that has a collapsing core, to understand its possible formation and evolution. We f…
Thermalization of electron-positron plasma with quantum degeneracy
M. A. Prakapenia, I. A. Siutsou, G. V. Vereshchagin
The non-equilibrium electron-positron-photon plasma thermalization process is studied using relativistic Boltzmann solver, taking into account quantum corrections both in non-relat…
Phenomenology at the LHC of composite particles from strongly interacting Standard Model fermions via four-fermion operators of NJL type
Roberto Leonardi, Orlando Panella, Francesco Romeo +3
A new physics scenario shows that four-fermion operators of Nambu-Jona-Lasinio (NJL) type have a strong-coupling UV fixed point, where composite fermions (bosons ) form as b…
Contraction of cold neutron star due to in the presence a quark core
B. Eslam Panah, T. Yazdizadeh, G. H. Bordbar
Motivated by importance of the existence of quark matter on structure of neutron star. For this purpose, we use a suitable equation of state (EoS) which include three different par…
MultiPulse {\it Fermi} Gamma-Ray Bursts. I. Evidence of the Transition from Fireball to Poynting-flux-dominated Outflow
Liang Li
The composition of a jet is still an unsolved problem in gamma-ray bursts (GRBs). Several previous studies have suggested that the prompt emission spectrum of GRBs is likely to con…
Novel constraints on fermionic dark matter from galactic observables II: galaxy scaling relations
C. R. Argüelles, A. Krut, J. A. Rueda +1
We have recently introduced in paper I an extension of the Ruffini-Argüelles-Rueda (RAR) model for the distribution of DM in galaxies, by including for escape of particle effects.…
On the energy content of electromagnetic and gravitational plane waves through super-energy tensors
Donato Bini, Andrea Geralico
The energy content of (exact) electromagnetic and gravitational plane waves is studied in terms of super-energy tensors (the Bel, Bel-Robinson and the --less familiar-- Chevreton t…
GW170817: implications for the local kilonova rate and for surveys from ground-based facilities
M. Della Valle, D. Guetta, E. Cappellaro +7
We compute the local rate of events similar to GRB 170817A, which has been recently found to be associated with a kilonova (KN) outburst. Our analysis finds an observed rate of suc…
Thermal fluctuations of charged black holes in gravity's rainbow
Sudhaker Upadhyay, Seyed Hossein Hendi, Shahram Panahiyan +1
Quantum fluctuation effects have an irrefutable role in high energy physics. Such fluctuation can be often regarded as a correction of infrared (IR) limit. In this paper, the effec…
Hyperbolic-like elastic scattering of spinning particles by a Schwarzschild black hole
Donato Bini, Andrea Geralico
The scattering of spinning test particles by a Schwarzschild black hole is studied. The motion is described according to the Mathisson-Papapetrou-Dixon model for extended bodies in…
