Abstract

We present a correlation analysis between the flux ratio of high-energy [FORMULA]-ray emission to synchrotron emission and the Doppler factor for a sample of EGRET AGNs. The result favors a model that attributes the EGRET emission of AGNs to inverse-Compton scattering on photons external to the jet.
