We present measurements and implications of the clustering of a large spectroscopic sample of luminous red galaxies from the Sloan Digital Sky Survey. The sample includes 55,000 galaxies over 3800 square degrees from redshift 0.16 to 0.47. We have measured the auto-correlation function on scales from 400 kpc to 200 Mpc, as well as the cross-correlation between the spectroscopic galaxies and 16 million galaxies from the SDSS imaging. On small scales, the sample reveals a strong pattern of luminosity and scale-dependent bias that is consistent with the galaxies residing in very massive halos. On large scales, the correlations probe the linear regime over a wide range of scales and are in excellent agreement with LCDM.
