Neutrino Properties from Cosmology

Cosmic background neutrinos are nearly as abundant as cosmic microwave background photons, but their mass, which determines the strength of their gravitational clustering, is unknown. Even if the neutrino masses are the minimum required by oscillation data, their gravitational effects on cosmological structure will nevertheless be detectable in — and in fact required to explain — data within the next decade. I will discuss the physical effects of the cosmic neutrino background on structure formation in the Universe and opportunities for determining the neutrino mass scale, and other neutrino properties, with future galaxy surveys and cosmic microwave background experiments.
