Diffusive photospheres in gamma-ray bursts
G. V. Vereshchagin, I. A. Siutsou
Photospheric emission may originate from relativistic outflows in two qualitatively different regimes:\ last scattering of photons inside the outflow at the photospheric radius, or…
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…
Numerical scheme for treatment of Uehling-Uhlenbeck equation for two-particle interactions in relativistic plasma
M. A. Prakapenia, I. A. Siutsou, G. V. Vereshchagin
We present a new efficient method to compute Uehling-Uhlenbeck collision integral for all two-particle interactions in relativistic plasma with drastic improvement in computation t…
What can we extract from quasi-periodic oscillations?
Kuantay Boshkayev, Donato Bini, Jorge Rueda +3
In light of the relativistic precession model, we present here detailed analyses, extending the ones performed in the Schwarzschild and Kerr spacetimes. We consider the kilohertz q…
Spreading of ultrarelativistically expanding shell: an application to GRBs
R. Ruffini, I. A. Siutsou, G. V. Vereshchagin
Optically thick energy dominated plasma created in the source of Gamma-Ray Bursts (GRBs) expands radially with acceleration and forms a shell with constant width measured in the la…
Monte Carlo simulations of the photospheric emission in GRBs
D. Bégué, I. A. Siutsou, G. V. Vereshchagin
We studied the decoupling of photons from ultra-relativistic spherically symmetric outflows expanding with constant velocity by means of Monte-Carlo (MC) simulation. For outflows w…
