The intrinsic γ-ray emissions of Fermi blazars

The beaming effect is important for understanding the observational properties of blazars.In this work, we collect 91 Fermi blazars with available radio Doppler factors. γ-ray Doppler factors are estimated and compared with radio Doppler factors for some sources. The intrinsic(de-beamed)γ-ray flux density(f_γ~(in)), intrinsic γ-ray luminosity(L_γ~(in)) and intrinsic synchrotron peak frequency(V_P~(in))are calculated. Then we study the correlations between finγand redshift and find that they follow the theoretical relation: log f =-2.0 log z + const. When the subclasses are considered, we find that stationary jets are perhaps dominant in low synchrotron peaked blazars. Sixty-three Fermi blazars with both available short variability time scales(?T) and Doppler factors are also collected. We find that the intrinsic relationship between L_γ~(in) and ?Tinobeys the Elliot Shapiro and Abramowicz Nobili relations. Strong positive correlation between f_γ~(in)and V_P~(in)is found, suggesting that synchrotron emissions are highly correlated with γ-ray emissions.
