Abstract

The second catalog of high-energy gamma-ray observations from the Energetic Gamma-Ray Experiment Telescope (EGRET) on the Campton Gamma Ray Observatory includes data from phase 1 (1991 April-1992 November) and phase 2 (1992 November-1993 September) of the mission. In addition to including more data than the first EGRET catalog, this catalog uses an improved model of the diffuse Galactic gamma radiation. The 129 sources in the catalog include one solar flare bright enough to be detected as a source, the Large Magellanic Cloud, five pulsars, 40 high-confidence identifications of active galactic nuclei (AGNs), 11 AGN identifications with lower confidence, and 71 sources not yet identified with known objects. Also included are approximate upper limits for gamma-ray sources at any point in the sky and information about sources listed in the first EGRET catalog but not appearing in this one.
