Did IceCube discover Dark Matter around Blazars?
Models of blazar jets, that explain observations of their photon spectra, typically predict too few neutrinos to be possibly seen by existing telescopes. In particular, they fall short in reproducing the first neutrino ever detected from a blazar, TXS 0506+056, by IceCube in 2017. We predict larger...

| description | Models of blazar jets, that explain observations of their photon spectra,
typically predict too few neutrinos to be possibly seen by existing telescopes.
In particular, they fall short in reproducing the first neutrino ever detected
from a blazar, TXS 0506+056, by IceCube in 2017. We predict larger neutrino
fluxes by using the same jet models, extended to include deep inelastic
scatterings between protons within the jet and sub-GeV dark matter (DM) around
the central black holes of blazars. In this way we succeed in explaining
neutrino observations of TXS 0506+056, for DM parameters allowed by all
laboratory, direct and indirect searches. Our proposal will be tested by DM
searches as well as by the observation of more neutrinos from blazars. Our
findings motivate to implement DM-nuclei interactions in jet models and to
improve our knowledge of DM spikes around active galactic nuclei. |
