Abstract
We find restrictions on the mass and mixing angle of the dark matter sterile neutrinos using x-ray observations of Coma and Virgo galaxy clusters with XMM-Newton satellite. In the absence of clearly detectable line, we present detailed analysis of various methods of putting restrictions on mass and mixing angle of sterile neutrino. Our analysis provides significant improvement over our previous results, coming from XRB background measurements. We also discuss restrictions from Virgo cluster by other authors and compare our results with them.Keywords
