Abstract:
High energy astronomy above 30 MeV received a significant impetus from the observations of EGRET (Energetic Gamma-Ray Experiment Telescope) on board the Compton Gamma Ray Observatory (CGRO). Until June 2000, when CGRO was de-orbited, EGRET produced a wealth of important astrophysical results, and was responsible for the detection of more than 270 point sources of gamma-rays. These sources include active galaxies, pulsars, the normal galaxy LMC, as well as the large majority of sources that remain unidentified. In addition, EGRET has detected the high energy emission from a few ?-ray bursts (GRBs). The article selectively reviews some of the important results from EGRET.
