Low luminosity active galactic nuclei are more abundant and closer to us than the luminous ones but harder explore as they faint. We have selected four sources NGC 315, 4261, 1275, 4486, which been detected in gamma rays byFermi-LAT. compiled their long-term radio, optical, X-ray data from different telescopes, analysed XMM-Newton for Swift 315. Fermi-LAT collected over period of 2008 2020 all ...
