Theory of photospheric emission in gamma-ray bursts

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

With the failure of the optically thin models to explain gamma-ray bursts (GRB) prompt emission, attention had been given to optically thick models. In these models, part of the observed spectrum originated from processes occurring below the photosphere, in regions of high optical depth. The photons are coupled to the plasma, and escape once they reach the photosphere. Various processes cause the observed spectra to differ than the naively expected “Planck” function. I describe recent developments in our understanding of emission from the photosphere, which may hold the key to understanding the physics of GRBs.
