BAO data from two decades of SDSS surveys rule out dark-energy-free models at more than eight standard deviations even when curvature is allowed.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

BAO data alone are able to rule out dark-energy-free models at more than eight standard deviations in an extension to the flat LambdaCDM model that allows for curvature; when combined with Planck CMB the BAO data provide nearly an order of magnitude improvement on curvature constraints.

C2weakest assumption

The analysis assumes that the sound horizon rd is accurately predicted by early-universe physics and that the spectroscopic samples have no significant unaccounted systematics in their clustering measurements.

C3one line summary

Final SDSS BAO and RSD data from galaxies, quasars, and Lyman-alpha forests confirm LambdaCDM, rule out dark-energy-free models at over 8 sigma, and give H0 = 68.20 +/- 0.81 km/s/Mpc in tension with local measurements.
