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.
