EGRET All-Sky Map

EGRET All-Sky Map


The EGRET all-sky map shows an image of the sky at gamma-ray energies above 100 MeV in Galactic coordinates. The diffuse emission, which appears brightest along the Galactic plane, is primarily due to cosmic-ray interactions with the interstellar medium. The Vela, Geminga and Crab pulsars are clearly visible as bright knots of emission in the Galactic plane in the right portion of the image. The blazar 3C279 is seen as the brightest knot of emission above the plane. This map was produced by combining EGRET observations from the first year of Compton Observatory operations.
