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.

活跃星系中心暗物质尖峰中的中微子产生

最近的多信使观测表明，高能中微子可能在活动星系中心黑洞附近产生。这些区域可能存在暗物质（DM）尖峰，其中DM粒子的浓度非常高。在这里，我们探讨了DM湮灭对中微子产生、质子-光子相互作用的目标光子的贡献，估计了相关的中微子谱，并找出了这种情况下可能的未来测试。
