• W2995898046 abstract "We present a joint analysis of the Planck cosmic microwave background (CMB) and Baryon Oscillation Spectroscopic Survey (BOSS) final data releases. A key novelty of our study is the use of a new full-shape (FS) likelihood for the redshift-space galaxy power spectrum of the BOSS data, based on an improved perturbation theory template. We show that the addition of the redshift-space galaxy clustering measurements breaks degeneracies present in the CMB data alone and tightens constraints on cosmological parameters. Assuming the minimal $mathrm{ensuremath{Lambda}}mathrm{CDM}$ cosmology with massive neutrinos, we find the following late-Universe parameters: the Hubble constant ${H}_{0}=67.9{5}_{ensuremath{-}0.52}^{+0.66}text{ }text{ }mathrm{km}text{ }{mathrm{s}}^{ensuremath{-}1}text{ }{mathrm{Mpc}}^{ensuremath{-}1}$, the matter density fraction ${mathrm{ensuremath{Omega}}}_{m}=0.307{9}_{ensuremath{-}0.0085}^{+0.0065}$, the mass fluctuation amplitude ${ensuremath{sigma}}_{8}=0.808{7}_{ensuremath{-}0.0072}^{+0.012}$, and an upper limit on the sum of neutrino masses ${M}_{mathrm{tot}}<0.16text{ }text{ }mathrm{eV}$ (95% C.L.). This can be contrasted with the Planck-only measurements: ${H}_{0}=67.1{4}_{ensuremath{-}0.72}^{+1.3}text{ }text{ }mathrm{km}text{ }{mathrm{s}}^{ensuremath{-}1}text{ }{mathrm{Mpc}}^{ensuremath{-}1}$, ${mathrm{ensuremath{Omega}}}_{m}=0.318{8}_{ensuremath{-}0.016}^{+0.0091}$, ${ensuremath{sigma}}_{8}=0.805{3}_{ensuremath{-}0.0091}^{+0.019}$, and ${M}_{mathrm{tot}}<0.26text{ }text{ }mathrm{eV}$ (95% C.L.). Our bound on the sum of neutrino masses relaxes once the hierarchy-dependent priors from the oscillation experiments are imposed. The addition of the new FS likelihood also constrains the effective number of extra relativistic degrees of freedom, ${N}_{mathrm{eff}}=2.88ifmmodepmelsetextpmfi{}0.17$. Our study shows that the current FS and the pure baryon acoustic oscillation data add a similar amount of information in combination with the Planck likelihood. We argue that this is just a coincidence given the BOSS volume and efficiency of the current reconstruction algorithms. In the era of future surveys FS will play a dominant role in cosmological parameter measurements." @default.
