Can Sterile Neutrinos Be Ruled Out as Warm Dark Matter Candidates?
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 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 a lower limit of mWDM …
