Theoretical predictions of spectral evolution of short GRBs

Astrophysics 2010-11-11 v1 General Relativity and Quantum Cosmology

Abstract

We present the properties of spectrum of radiation emitted during gravitational collapse in which electromagnetic field strengths rise over the critical value for e+ee^+e^- pair creation. A drift from soft to a hard energy and a high energy cut off have been found; a comparison with a pure black body spectrum is outlined.
