  We demonstrate for the first time that three sterile neutrinos alone can
simultaneously explain neutrino oscillations, the observed dark matter and the
baryon asymmetry of the Universe without new physics above the Fermi scale. The
key new point of our analysis is leptogenesis after sphaleron freeze-out, which
leads to resonant dark matter production, evading thus the constraints on
sterile neutrino dark matter from structure formation and x-ray searches. We
identify the range of sterile neutrino properties that is consistent with all
known constraints. We find a domain of parameters where the new particles can
be found with present day experimental techniques, using upgrades to existing
experimental facilities.
