Restrictions on sterile neutrino parameters from astrophysical observations

Understand

Adding 3 right-handed (sterile) neutrino to the Standard Model (SM) can solve several "beyond the Standard Model" problems within one consistent framework: explain neutrino oscillations and baryon asymmetry of the Universe and provide a dark matter (DM) candidate.

• In this talk I will present current status of astrophysical searches for the DM sterile neutrino.
