Description
The IceCube Collaboration has recently reported compelling evidence of high energy neutrino emission from NGC 1068, and mild excesses for NGC 4151 and CGCG420- 015, local Seyfert galaxies. This has increased the interest along neutrino emission from hot corona surrounding the super massive black holes of Seyfert Galaxies. In this contribution, I demonstrate that these sources are consistent with sub-equipartition between CR and the magnetic energy densities. Nonetheless, the energetics carried by CRs is rather high, making future analyses fundamental to investigate if such conditions can be met in the environment of seyfert galaxies. I will estimate the neutrino flux of the whole seyfert population, and I will demonstrate that it might overestimate the diffuse neutrino flux at 1-10 TeV energies leading to a potential tension in the high-energy neutrino sky. I argue that not all the AGNs might be neutrino emitters. All in all, all these results point to the fact that regions surrounding the SBMHs in AGNs might be able to accelerate cosmic rays producing high-energy neutrinos.
