Spectral Modeling of GRB Pulses

Astrophysics 2007-05-23 v1

Abstract

The energy spectra of pulses of GRBs are modeled for synchrotron and multiple self-inverse Compton scatterings from a population of thermal and non-thermal ee^-s. The contribution from pairs that result from annihilation is also taken into account. A high particle density (enhanced by the pairs) will increase absorption but, if the pairs are not accelerated, the absorption frequency cannot lie in the BATSE window. Pairs will contribute in upscattering and will most likely increase the population of cold particles that will downscatter hard photons and thus suppress hard (e.g., above 300 keV) emission.
