Relic neutrinos: neutrino properties from cosmology
Abstract
Description
After a short introduction on the predicted cosmic neutrino background in the universe, we review some of the cosmological bounds related to neutrinos. In particular we show how the recent data on the anisotropies of the cosmic microwave background radiation from the WMAP satellite, combined with other experimental results, can constrain the radiation content of the universal energy density and the sum of neutrino masses.
