Can sterile neutrinos be ruled out as warm dark matter candidates?
We present constraints on the mass of Warm Dark Matter (WDM) particles from a combined analysis of the matter power spectrum inferred from the SDSS (Sloan Digital Sky Survey) Lyman-alpha flux power spectrum at 2.2<z<4.2, cosmic microwave background data and the galaxy power spectrum. We obtain...
