Physics of non-dissipative ultrarelativistic photospheres
Gregory Vereshchagin
Recent observations, especially by the Fermi satellite, point out the importance of the thermal component in GRB spectra. This fact revives strong interest in photospheric emission…
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…
Comptonization of photons near the photosphere of relativistic outflows
A. G. Aksenov, R. Ruffini, G. V. Vereshchagin
We consider the formation of photon spectrum at the photosphere of ultrarelativistically expanding outflow. We use the Fokker-Planck approximation to the Boltzmann equation, and ob…
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…
