DETECTION OF GAMMA RAYS WITH E[ 100 MeV FROM BL LACERTAE

Abstract

We present evidence for the Ðrst detection of gamma rays from the extragalactic object BL Lacertae. Observations taken with EGRET on the Compton Gamma Ray Observatory between 1995 January 24 and 1995 February 14 indicate a 4.4 p excess from the direction of BL Lacertae. The corresponding Ñux is (40^ 12) ] 10~8 photons cm~2 s~1 above 100 MeV. The combination… (More)
