Constraints on the parameters of radiatively decaying dark matter from the dark matter halo of the Milky Way and Ursa Minor
Using the recent XMM-Newton PN blank sky data, we improve the earlier restrictions on parameters of the warm dark matter (DM) in the form of sterile neutrino (by as much as the order of magnitude at masses ~ 3.5 kev). The results are obtained from non-observing DM decay line in the X-ray spectrum of...
