We demonstrate that three sterile neutrinos can simultaneously explain neutrino oscillations, the observed dark matter and baryon asymmetry of the Universe. We perform the first complete study to identify the range of sterile neutrino properties consistent with these requirements, combining the study of neutrino abundances and lepton asymmetries in the early universe with bounds from nucleosynthesis and direct searches. We find that there is a domain of parameters where all these particles can be found with present day experimental techniques, using upgrades to existing experimental facilities.
