Constraining Supernova Ia Progenitors by their Locations in Host Galactic Disc

A. A. Hakobyan, A. G. Karapetyan, L. V. Barkhudaryan

Among the diverse progenitor channels leading to Type Ia Supernovae (SNe Ia), there are explosions originating from white dwarfs with sub-Chandrasekhar masses. These white dwarfs u…

Pauli blocking effects on pair creation in strong electric field

Mikalai Prakapenia, Gregory Vereshchagin

The process of electron-positron pair creation and oscillation in uniform electric field is studied, taking into account Pauli exclusion principle. Generally, we find that pair cre…

Electromagnetic radiation and electromagnetic self-force of a point charge in the vicinity of Schwarzschild black hole

S. O. Komarov, A. K. Gorbatsievich, A. S. Garkun +1

Point charge, radially moving in the vicinity of a black hole is considered. Electromagnetic field in wave zone and in the small neighbourhood of the charge is calculated. Numerica…

Is magnetically dominated outflow required to explain GRBs?

Gregory Vereshchagin, Liang Li, Damien Bégué

The composition of relativistic outflows producing gamma-ray bursts is a long standing open question. One of the main arguments in favor of magnetically dominated outflows is the a…

Numerical scheme for evaluating the collision integrals for triple interactions in relativistic plasma

M. A. Prakapenia, I. A. Siutsou, G. V. Vereshchagin

Binary interactions in relativistic plasma, such as Coulomb and Compton scattering as well as pair creation and annihilation are well known and studied in details. Triple interacti…

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…
