We present a correlation analysis between the flux ratio of high-energy gamma-ray emission to synchrotron emission and the Doppler factor for a sample of EGRET AGNs. The results favor a model that attributes the EGRET emission of AGNs to inverse-Compton scattering on photons external to the jet.
After comparing the flux densities of a sample of active galactic nuclei detected by energetic gamma-ray experiment telescope at 90 and 230 GHz with the $γ$-ray emissions detected by Compton Gamma Ray Observatory and x-ray emission, a strong correlation between the emissions at the millimeter wavelength and the $γ$-ray emission is found. The average flux density of x-ray is almost proportional to the average flux density at the millimeter wavelength for quasars detected by energetic gamma-ray experiment telescope, which strongly supports the previous idea that the x-ray emissions of this kind sources are mainly produced by Synchrotron Self-Compton process.
