Abstract

The most identified sources observed by Fermi are blazars (Flat Spectrum Radio Quasars (FSRQs) and BL Lacertae objects (BLs). In this paper, we obtained 124 γ-ray loud blazars with available γ-ray and radio (core and total) data. It is interesting that the γ-ray luminosity have a good correlation with the radio luminosity. This phenomenon exists in the core radio luminosity (Lc) and total radio luminosity (Lt). The correlation between the γ-ray and the radio luminosities is still stronger even after we eliminated the redshift effect, which suggests that the γ-ray radiations in the γ-ray loud blazars are strongly beamed.
