Resum
We present distance scale measurements from the baryon acoustic oscillation signal in the constant stellar mass and low-redshift sample samples from the Data Release 12 of the Baryon Oscillation Spectroscopic Survey. The total volume probed is 14.5 Gpc(3), a 10 per cent increment from Data Release 11. From an analysis of the spherically averaged correlation function, we infer a distance to z = 0.57 of Mpc and a distance to z = 0.32 of Mpc assuming a cosmology in which Mpc. From the anisotropic analysis, we find an angular diameter distance to z = 0.57 of Mpc and a distance to z = 0.32 of 981 +/- 20 Mpc, a 1.5 and 2.0 per cent measurement, respectively. The Hubble parameter at z = 0.57 is km s(-1) Mpc(-1) and its value at z = 0.32 is 79.2 +/- 5.6 km s(-1) Mpc(-1), a 3.7 and 7.1 per cent measurement, respectively. These cosmic distance scale constraints are in excellent agreement with a I > cold dark matter model with cosmological parameters released by the recent Planck 2015 results.
