dc.description.abstract | We measure the growth rate and its evolution using the anisotropic clustering of the extended Baryon Oscillation Spectroscopic Survey (eBOSS) Data Release 14 (DR14) quasar sample, which includes 148 659 quasars covering the wide redshift range of 0.8 < z < 2.2 and a sky area of 2112.90 deg2. To optimize measurements we deploy a redshift-dependent weighting scheme, which allows us to avoid binning and perform the data analysis consistently including the redshift evolution across the sample. We perform the analysis in Fourier space, and use the redshift evolving power spectrum multipoles to measure the redshift-space distortion parameter fσ8 and parameters controlling the anisotropic projection of the cosmological perturbations. We measure fσ8(z = 1.52) = 0.43 ± 0.05 and dfσ8/dz(z = 1.52) = -0.16 ± 0.08, consistent with the expectation for a lambda cold dark matter cosmology as constrained by the Planck experiment. | |
