EGRET Observations of Gamma-Ray Bursts
Abstract
The intense gamma-ray burst of January 31, 1993 was detected by the Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Observatory. Sixteen gamma-rays above 30 MeV were imaged in the telescope. Two of these gamma-rays have energies of approximately 1 GeV, and the 5 bin spectrum of the 16 events is fit by a power law of photon spectral index -2.0+/-0.4. These gamma-rays were detected over a 25 second time interval. This observation increases by an order of magnitude the energy of gamma-rays detected in a gamma-ray burst and places severe constraints on the many theoretical models of gamma-ray bursts.
