A Bulk Comptonization Model for the Prompt GRB Emission and its Relation to the Fermi GRB Spectra
Author and Affiliation:
Kazanas, Demosthenes(NASA Goddard Space Flight Center, Greenbelt, MD, United States)
Abstract: We present a model in which the GRB prompt emission at E ~ E(sub peak) is due to bulk Comptonization by the relativistic blast wave motion of either its own synchrotron photons of ambient photons of the stellar configuration that gave birth to the GRB. The bulk Comptonization process then induces the production of relativistic electrons of Lorentz factor equal to that of the blast wave through interactions with its ambient protons. The inverse compton emission of these electrons produces a power law component that extends to multi GeV energies in good agreement with the LAT GRB observations.
