Description
We summarize the status of dark matter indirect searches using neutrinos as messengers, and we point out that dark matter spikes around supermassive black holes can enhance significantly the neutrino flux from nearby galaxies, possibly even at the reach of neutrino telescopes. In particular, we propose that the measured neutrino flux from NGC1068 could be attributed to dark matter annihilations, for parameters escaping detection from the Milky Way center, due to the strong stellar heating of the spike in the latter.
