The Compton Gamma-Ray Observatory (CGRO) experiments EGRET and COMPTEL observed the Virgo sky region continuously for 7 weeks between December 10, 1996 and January 28, 1997. The prominent quasar 3C 273 was found to be the brightest source in γ-rays and was significantly detected by EGRET and COMPTEL. The EGRET experiment observed a time-variable flux at(More)
During the CGRO observations in the years 1991 to 1995, the region on the sky including the active radio galaxy Centaurus A, was in the wide eld-of-view of COMPTEL and EGRET in 15 pointings of various durations. During some of these pointings, also OSSE made simultaneous observations of Cen A. BATSE, the fourth instrument on CGRO, continuously monitors this(More)
During the Compton Gamma-Ray Observatory (CGRO) observations made in Phase I, II, III, and IV/Cycle 4 in the years 1991 to 1995, the region on the sky including the radio galaxy Centaurus A was in the wide field-of-view of COMPTEL in 15 pointings of various durations. The analysis of the COMPTEL data obtained during these 15 pointings shows emission(More)
