Abstract

Fitting the predictions of the ?CDM model to the Sachs-Wolfe effect, s₈, the galaxy power spectrum P_gal(k), fluctuations of galaxy counts in spheres of radii ranging from 16/h to 128/h Mpc, Baryon Acoustic Oscillation (BAO) measurements, and h = 0.678 ± 0.009, in various combinations, with free spectral index n_s, and free galaxy bias and galaxy bias slope, we obtain consistent measurements of the sum of neutrino masses ? m_? . The results depend on h, so we have presented confidence contours in the (? m_? , h) plane.
