Abstract

We show that galaxy redshift surveys provide an extraordinarily sensitive probe of the neutrino mass, with eV mass neutrinos suppressing the power spectrum by a factor of two. The upcoming Sloan Digital Sky Survey should detect N nearly degenerate massive neutrino species with mass m_\nu > 0.65 (\Omega_m h^2/0.1 N)^{0.8} eV at better than 2\sigma once cosmic microwave background experiments, which are themselves insensitive to m_\nu, measure two other cosmological parameters. There is significant overlap between this region and that implied by the LSND experiment, and even m_\nu ~ 0.1 eV, as implied by the atmospheric neutrino anomaly, can affect cosmological measurements.
