Further evidences of superluminal AGNs as \(\gamma\)-ray sources

In our previous work in Xiao et al. (2019), we suggested that 6 superluminal sources could be gamma-ray candidates, and in fact 5 of them have been confirmed in the fourth Fermi-LAT source catalogue (4FGL). In this work, based on the 4FGL, we report a sample of 229 Fermi detected superluminal source...

Description
Summary:In our previous work in Xiao et al. (2019), we suggested that 6 superluminal sources could be gamma-ray candidates, and in fact 5 of them have been confirmed in the fourth Fermi-LAT source catalogue (4FGL). In this work, based on the 4FGL, we report a sample of 229 Fermi detected superluminal sources (FDSs) including 40 new FDSs and 62 non-Fermi detected superluminal sources (non-FDSs). Thus, we believe that all superluminal sources should have \(\gamma\)-ray emissions, and superluminal motion could also be a clue to detect \(\gamma\)-ray emission from active galactic nuclei (AGN). We present a new approach of Doppler factor estimate through the study of the \(\gamma\)-ray luminosity (\(L_{\rm \gamma}\)) and of the viewing angle (\(\phi\)).
