    Abstract

    The absolute neutrino mass scale is currently unknown, but can be constrained by cosmology. The WiggleZ high redshift, star-forming, and blue galaxy sample offers a complementary data set to previous surveys for performing these measurements, with potentially different systematics from nonlinear structure formation, redshift-space distortions, and galaxy bias. We obtain a limit of m ν<0.60eV (95% confidence) for WiggleZ+WilkinsonMicrowaveAnisotropyProbe. Combining with priors on the Hubble parameter and the baryon acoustic oscillation scale gives m ν<0. 29eV, which is the strongest neutrino mass constraint derived from spectroscopic galaxy redshift surveys.
