Very high efficiency photospheric emission in long duration gamma-ray bursts
Davide Lazzati, Brian J. Morsony, Mitch Begelman
We numerically analyze the evolution of a long-duration gamma-ray burst jet as it leaves the progenitor star and propagates to the photospheric radius, where radiation can be relea…

Fast TeV variability in blazars: jets in a jet
Dimitrios Giannios, Dmitri A. Uzdensky, Mitchell C. Begelman
The fast TeV variability of the blazars Mrk 501 and PKS 2155--304 implies a compact emitting region that moves with a bulk Lorentz factor of Gamma_{em}~100 toward the observer. The…
