Abstract
We have used the SAS-2 γ-ray data to search for γ-rays of energy >100 MeV from extragalactic active galactic nuclei (AGNs). The correlation function devised by the COS-B group to search for galactic γ-ray sources has been used. We have identified 18 such AGNs, including 13 quasars, 3 BL Lac objects, 1 Seyfert galaxy and 1 radiogalaxy. We have further investigated the relationship between the γ-ray fluxes in the energy regions > 100 MeV and 35–100 MeV and their redshifts, and we have also derived their γ-ray spectral indices. The results give further support to our claim that the sources detected are genuine extragalactic objects.
