TeV to PeV neutrinos from AGN coronae
Abstract
Abstract In this paper, we attempt to explain the TeV-sub PeV neutrinos observed by IceCube assuming that their sources are active galactic nuclei (AGN). The results are obtained in the model where the thermal accretion disc emits in the UV-optical range inside the hot electron plasma cloud. We focus on the analytical solution for the comptonization problem obtained from consideration at the microscopic level and try to avoid fitting the coronal spectrum from spectral observations. Using the Monte-Carlo approach to model photopion interactions in the central regions of AGN and then after taking into account the cosmological evolution it is shown that within the framework of this approach it is possible to describe both ∼ 100 TeV and sub PeV neutrinos from AGN taking into account only photohadronic interactions.
