Scientific paper

Measurements of galaxy clustering are presented from the Baryon Oscillation Spectroscopic Survey (BOSS), using the Data Release 9 (DR9). This sample contains approximately 275,000 massive galaxies, out to redshift 0.7 covering 3,200 square degrees. This BOSS DR9 sample represents the largest sample of the Universe ever surveyed at this density, which is sufficient to ensure that our measurements are cosmic variance limited. We present multipoles of the correlation function and the spherically averaged power spectrum measured from these data. The acoustic features are detected at high significance, a clear indication that the evolution of the Universe on large-scales follows standard linear theory.
