We present the analysis of full shape anisotropic clustering measurement from extended Baryon Oscillation Spectroscopic Survey (eBOSS) quasar sample together with combined galaxy (BOSS), re-analysed using an updated recipe for non-linear matter power spectrum and non-local bias parameters. obtain constraints flat $\Lambda$CDM cosmologies, focusing on cosmological parameters that are independent Hubble parameter $h$. Our recovered value RMS linear perturbation theory variance as measured...
We analyse the full shape of anisotropic clustering measurements from extended Baryon Oscillation Spectroscopic survey (eBOSS) quasar sample together with combined galaxy Survey (BOSS). obtain constraints on cosmological parameters independent Hubble parameter $h$ for extensions $\Lambda$CDM models, focusing cosmologies free dark energy equation state $w$. combine those latest CMB data Planck to joint these $w$ and additional extension - its time evolution $w_{\rm{a}}$, physical curvature...
ABSTRACT Standard full-shape clustering analyses in Fourier space rely on a fixed power spectrum template, defined at the fiducial cosmology used to convert redshifts into distances, and compress cosmological information Alcock–Paczynski parameters linear growth rate of structure. In this paper, we propose an analysis method that operates directly parameter varies template accordingly each tested point. Predictions for multipoles from TNS model are computed different cosmologies framework...
