Imposing a prior from Big Bang Nucleosynthesis on the baryon density, we are able to measure all the parameters in $\\Lambda$CDM + massive neutrinos in normal hierarchy, except for the total neutrino mass, which is just bounded. When combining the BOSS Full Shape with the Baryon Acoustic Oscillation measurements from BOSS, 6DF/MGS and eBOSS, we determine the present day Hubble constant, $H_0$, the present matter fraction, $\\Omega_m$, the amplitude of the primordial power spectrum, $A_s$, and the tilt of the primordial power spectrum, $n_s$, to $1.4 \\%, 4.5 \\%, 23.5\\%$ and $7.6\\%$ precision, respectively, at $68 \\%$-confidence level, finding $H_0=68.19 \\pm 0.99$ (km/s)/Mpc, $\\Omega_m=0.309\\pm 0.014$, $\\ln (10^{10}A_{s })=3.12^{+0.21}_{-0.26}$ and $n_s=0.963^{+0.062}_{-0.085}$, and we bound the total neutrino mass to $0.87 \\, \\textrm{eV}$ at $95 \\%$-confidence level. These constraints are fully consistent with Planck results and the ones obtained from BOSS power spectrum analysis. In particular, we find no tension in $H_0$ or $\\sigma_8$ with Planck measurements, finding consistency at $1.2\\sigma$ and $0.6\\sigma$, respectively.","url_abs":"https://arxiv.org/abs/2110.07539v3","url_pdf":"https://arxiv.org/pdf/2110.07539v3.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"boss-correlation-function-analysis-from-the","repo_url":"https://github.com/pierrexyz/pybird","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
