简介
We measure cosmological parameters using the three-dimensional power spectrum P (k) from over 200 000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with Wilkinson Microwave Anisotropy Probe (WMAP) and other data. Our results are consistent with a “vanilla” flat adiabatic cold dark matter model with a cosmological constant without tilt (n s= 1), running tilt, tensor modes, or massive neutrinos. Adding SDSS information more than halves the WMAP-only error bars on some parameters, tightening 1 σ constraints on the Hubble parameter from h≈ 0.74− 0.07+ 0.18 to h≈ 0.70− 0.03+ 0.04, on the matter density from Ω m≈ 0.25±0.10 to Ω m≈ 0.30±0.04 (1 σ) and on neutrino masses from< 11 to< 0.6 eV (95%). SDSS helps even more when dropping prior assumptions about curvature, neutrinos, tensor modes and the equation of state. Our results are in substantial agreement with the joint analysis …
