Interaction of GRB Fireballs with Ambient Medium
Andrei M. Beloborodov
The customary picture of the fireball deceleration by an external medium neglects two physical agents in the problem that are important at radii R<10^{17} cm: a radiative precursor…
Fireballs with a Neutron Component
Andrei M. Beloborodov
Standard GRB fireballs must carry free neutrons. This crucially changes the mechanism of fireball deceleration by an external medium. As the ion fireball decelerates, the coasting…
Early GRB Afterglows Revisited
Andrei M. Beloborodov
The standard afterglow model neglects the presence of the GRB prompt radiation ahead of the blast wave. In fact, the blast wave is dramatically influenced by the leading gamma-ray…
Prompt Emission and Early Afterglows of Gamma-Ray Bursts
Andrei M. Beloborodov
Observations and models of GRBs are reviewed with an emphasis on the early phase of the burst. Recent revision of the early afterglow model is described.
Power Density Spectra of Gamma-Ray Bursts
Andrei M. Beloborodov
Power density spectra (PDSs) of long gamma-ray bursts provide useful information on GRBs, indicating their self-similar temporal structure. The best power-law PDSs are displayed by…
Accretion Disk Models
Andrei M. Beloborodov
Models of black hole accretion disks are reviewed, with an emphasis on the theory of hard X-ray production. The following models are considered: i) standard, ii) super-critical, ii…
