We present a generalized neutrino luminosity function for protons accelerated in the coronae of supermassive black holes (SMBH) in Seyfert-like galaxies. The neutrino luminosity mainly depends on the coronal X-ray luminosity and SMBH mass. Our results suggest that the cosmologically-integrated neutrino luminosity could match the extragalactic diffuse IceCube signal below PeV levels. We conclude that the source-dependent proton luminosity associated with such neutrinos is energetically-significant and is capable of driving mildly relativistic coronal outflows and potentially of contributing to feedback processes. |
