Coronal Neutrino Luminosity and Implications for the Diffuse Extragalactic Neutrino Background

Rostom Mbarek, Princeton

Abstract: We present a generalized neutrino luminosity function for protons accelerated in the coronae of supermassive black holes (SMBHs) in Seyfert-like galaxies. The resulting neutrino luminosity depends primarily on the coronal x-ray luminosity and the system's magnetization, with a weaker dependence on SMBH mass. Our results suggest that the cosmologically integrated neutrino emission from these systems could account for the diffuse extragalactic IceCube signal at sub-PeV energies.
