The first fit to the anisotropic clustering of CMASS galaxies on scales of 0.8 - 32 Mpc/h

A 2.5% measurement of the growth rate from small-scale redshift space clustering of SDSS-III CMASS galaxies

We perform the first fit to the anisotropic clustering of the anisotropic clustering of the sloan digital sky survey-iii (sdss-iii) galaxy survey (sdss-iii) on large scales of @xmath0 - @xmath1 mpc/h.A standard halo occupation distribution model evaluated near the best fit planck lcdm cosmology provides a good fit to the observed anisotropic clustering, and implies a normalization for the velocity field of m ~ 2 x 10^13 msun/h halos of f*sigma8(z=0.57) = 0.447 +/- 0.028, the tightest single constraint on the growth rate of cosmic structure to date.Our measurement represents a factor of 2.5 improvement in precision over the analysis of dr11 on large scales, f*sigma8(z=0.57) = 0.447 +/- 0.028, and is consistent with the planck lcdm prediction of 0.480 +/- 0.010 at the 1.9 sigma level.
