Neutrino production in the central dark-matter spikes of active galaxies
arXiv:2410.09500 · doi:10.1140/epjc/s10052-025-14848-w
Abstract
Recent multi-messenger observations suggest that high-energy neutrinos may be produced close to central black holes in active galaxies. These regions may host dark-matter (DM) spikes, where the concentration of DM particles is very high. Here we explore the contribution of the DM annihilation to the target photons for the neutrino production, proton-photon interactions, estimate the associated neutrino spectrum and figure out possible future tests of this scenario.
