Abstract

Abstract: In this work, we investigated the correlation between the γ-ray luminosity, log L γ and the core-dominance parameter, log (1+ R ), for a sample of 124 Fermi blazars with available core and extended radio emissions. Our analysis shows that there is no correlation between the γ-ray luminosity, log L γ and the core-dominance parameter, log (1+ R ). However, there is a closely linear correlation between log L γ − log L Ext and log (1+ R ), log L γ −log L Ext = (0.95 ± 0.08) log (1+ R ) + (2.72 ± 0.11), for the whole sample. The result suggests that the γ-ray emissions are composed of two components, one is beamed, the other is unbeamed.
