Energetic Gamma-Ray Experiment Telescope—A gamma-ray telescope designed to study faint point-source and diffuse emissions, on NASA's Compton Gamma-Ray Observatory.
Energetic Gamma Ray Experiment Telescope on board the Compton Gamma Ray Observatory (operated from 30 M eV to 30 GeV).
Acronym for Energetic Gamma Ray Experiment Telescope on board the Compton Gamma Ray Observatory. EGRET has detected photons as energetic as 9 GeV as late as 90 minutes after the onset of a GRB event.
Energetic Gamma-Ray Experiment Telescope on the Compton Gamma-Ray Observatory (CGRO). This instrument has carried out an all-sky survey in many energy bands, along with dedicated pointed observations of particularly interesting or variable objects.
