COS B observation of high-energy γ radiation from 3C273
Abstract
THE discovery of a high-energy γ-ray source at α(1950) = 12h 29 min+/-6 min, δ(1950)= +3°+/-1.5° is reported here. Arguments are given for the identification with 3C273. If this identification is correct, the γ-ray luminosity of 3C273 in the energy range 50-500 MeV is 2×1046 erg s-1 for H0 = 60 km s-1 Mpc-1.
