Analysis reveals neutrino production mechanisms in proximity to black holes, indicating dark matter's potential role.
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.
