摘要: We analyse the anisotropic clustering of massive galaxies from Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic (BOSS) Data Release 9 (DR9) sample, which consists 264 283 in redshift range 0.43 0.57, and when combined imply ΩΛ = 0.74 ± 0.016, independent Universe's evolution at z < 0.57. All these constraints assume scale-independent linear growth, general relativity to compute both (10 per cent) non-linear model corrections our errors. In companion paper, Samushia et al., we explore further cosmological implications observations.
