The Clustering of Galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Measuring growth rate and geometry with anisotropic clustering
Monthly Notices of the Royal Astronomical Society(2014)
摘要
We use the observed anisotropic clustering of galaxies in the Baryon Oscillation Spectroscopic Survey Data Release 11 CMASS sample to measure the linear growth rate of structure, the Hubble expansion rate and the comoving distance scale. Our sample covers 8498 deg2 and encloses an effective volume of 6 Gpc3 at an effective redshift of $\bar{z} = 0.57$. We find fσ8 = 0.441 ± 0.044, H = 93.1 ± 3.0 k...
