Description
We analyse the large-scale correlation function of the 6dF Galaxy Survey (6dFGS) and detect a baryon acoustic oscillation (BAO) signal at 105h-1Mpc. The 6dFGS BAO detection allows us to constrain the distance-redshift relation at zeff= 0.106. We achieve a distance measure of DV(zeff) = 457 ± 27Mpc and a measurement of the distance ratio, rs(zd)/DV(zeff) = 0.336 ± 0.015 (4.5 per cent precision), where rs(zd) is the sound horizon at the drag epoch zd. The low-effective redshift of 6dFGS makes it...[Show more]
