At large separation scales the baryon acoustic oscillation (BAO) signal is detected which allows to make an absolute distance measurement at $z_{\\rm eff} = 0.106$. Such a measurement can be used to constrain the Hubble constant, $H_0 = 67.0\\pm3.2\\;$km s$^{-1}\\;$Mpc$^{-1}$ (4.8% precision).\n  Modelling the 2D galaxy correlation function of 6dFGS, $\\xi(r_p,\\pi)$, allows a measure of the parameter combination $f(z_{\\rm eff})\\sigma_8(z_{\\rm eff}) = 0.423 \\pm 0.055$, where $f \\simeq \\Omega_m^{\\gamma}(z"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1303.3302","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
