Neutrino mass from future large scale structure surveys

Abstract

We examine whether future, nearly all-sky spectroscopic galaxy surveys and photometric galaxy-cluster catalogs, as the ESA Euclid satellite, in combination with CMB priors, will be able to detect the signature of the cosmic neutrino background and determine the absolute neutrino mass scale. We find that the sensitivity of such future surveys is well suited to span the entire range of neutrino masses allowed by neutrino oscillation experiments, and to yield a clear detection of non-zero neutrino mass.
