Updates on Blazar-Boosted Dark Matter |
Résumé |
Blazars are Active Galactic Nuclei shooting jets of relativistic particles in the
direction of the Earth. Due to their powerful and peculiar features, blazars are
natural laboratories to probe extreme physics. For instance, the ultra-high-energy
protons and electrons in the extremely powerful jets of blazars can boost to very
high-energy via elastic collisions the dark matter (DM) particles in the
surroundings of the source. The blazar-boosted DM flux at Earth may be sizeable
and relevant to access direct detection for DM particle masses lighter than 1 GeV,
both with target nuclei and/or electrons. Concentrating on the source TXS 0506+056
-- from which IceCube reported evidence for a high-energy neutrino flux -- I will
review the limits that can be imposed on the DM-nucleon and DM-electron scattering
cross sections given the null detection at terrestrial facilities. |
