Description
Recent cosmological data favor additional relativistic degrees of freedom beyond the three active neutrinos and photons. Light sterile neutrinos are prime candidates for such additional radiation. I will discuss the evolution of light sterile neutrinos in the early universe, their role as dark-radiation candidates and present cosmological constraints.
