Abstract
  • Gamma ray bursts (GRBs) are short, intense pulses of gamma rays that emit radiation in a narrow beam. Unless the beam is oriented towards the observer, it is often difficult to resolve the bursts against the diffuse gamma ray background (DGRB). The DGRB is a measured source of gamma rays that is known to come from a variety of different sources. Between photon energies of approximately 200keV and 600keV, it is not fully known what sources contribute to the observed gamma rays. In this thesis we use a blob-cone model to simulate a population of unresolved gamma ray bursts in this energy region. We find that using a simplified set of burst parameters allows off-axis gamma ray bursts to account for only 1−7% of the observed gamma ray background.
