CGRO COMPTEL Observations of AGNs
Abstract
During its first year of operation, the imaging Compton telescope COMPTEL aboard the Compton Gamma Ray Observatory has searched the sky for medium-energy gamma-ray emission (0.7 to 30 MeV) from AGNs and quasars. We report on the detections of the quasars 3C273 and 3C279, PKS 0528+134, and the radio galaxy Cen A. Skymaps and preliminary spectra for these objects will be presented. Evidence for spectral breaks and possible time variability in the high-energy emission from these sources will be discussed. A brief status report on the search for medium-energy gamma radiation from other gamma-ray AGNs discovered by the high-energy EGRET experiment aboard the CGRO will also be presented.
