Sterile neutrino Warm Dark Matter constraints from XMM-Newton and INTEGRAL/SPI observations

Abstract. The existence of right-handed "sterile" neutrinos can explain such phenomena as neutrino oscillations, origin of dark matter particles and baryon assymetry of the Universe. We present the upper limits on "sterile" neutrino parameters, obtained from direct observations of dark matter clusters (central parts of Milky Way and Andromeda galaxies), and discuss the physical consequences of these limits.
