Phys. Rev. Lett. 80, 5255–5258 (1998)Weighing Neutrinos with Galaxy SurveysReceived 3 December 1997; revised 13 March 1998; published in the issue dated 15 June 1998 We show that galaxy redshift surveys sensitively probe the neutrino mass, with eV mass neutrinos suppressing power by a factor of 2. The Sloan Digital Sky Survey can potentially detect N nearly degenerate massive neutrino species with mass mν≳0.65(Ωmh2/0.1N)0.8 eV at better than 2σ once microwave background experiments measure two other cosmological parameters. Significant overlap exists between this region and that implied by the Liquid Scintillator Neutrino Detector experiment, and even mν∼0.01–0.1 eV, as implied by the atmospheric anomaly, can affect cosmological measurements. © 1998 The American Physical Society URL:
