The sterile neutrino is a plausible dark matter candidate that emits an X-ray through radiative decay. We initiated the first dedicated X-ray search for dark matter, deriving new constraints on sterile neutrinos from Suzaku data on the Ursa Minor dwarf spheroidal galaxy, and a marginal detection of a sterile neutrino line at 2.5 keV in the extreme dark matter dwarf spheroidal Willman 1. This tentative detection can only be tested utilizing XMM-Newton EPIC. We propose 75-100 ksec observations (including offset pointings) of Willman 1, as well as Segue 1 and Ursa Major II. Confirmation by XMM-Newton would be of incomparable astrophysical importance, pointing the way to new physics, and implying that future X-ray spectroscopic missions will directly map the dark distribution and its evolution.
