DOIAbstract
We explore the cosmological implications of the clustering wedges, ξ⊥(s) and ξ∥(s), of the CMASS Data Release 9 sample of the Sloan Digital Sky Survey III (SDSS-III) Baryon Oscillation Spectroscopic Survey. These clustering wedges are defined by averaging the full two-dimensional correlation function, ξ(μ, s),over the ranges 0 <μ <0.5 and 0.5 <μ <1,respectively. These measurements allow us to constrain the parameter combinations DA(z)/rs(zd) = 9.03± 0.21 and cz/(rs(zd)H(z)) = 12.14 ±0.43 at the mean redshift of the sample, z = 0.57. We combine the information from the clustering wedges with recent measurements of cosmic microwave background (CMB), baryon acoustic oscillations and TypeIa supernovae to obtain constraints on the cosmological p...
