RED GALAXY CLUSTERING IN THE NOAO DEEP WIDE-FIELD SURVEY

We present measurements of the clustering of 0.3<z<1.5 red galaxies and extremely red objects (EROs) using subsamples selected from the NOAO Deep Wide-Field Survey (NDWFS). The complete NDWFS is a survey of 18 square degrees at high galactic latitudes to depths of Bw=27, R=26, I=25 and K=19. Lambda CDM models of large-scale structure evolution and galaxy formation predict mild evolution of the galaxy correlation function at z<2. However, previous observational studies using apparent magnitude limited samples conclude the galaxy correlation function undergoes rapid evolution at z<1.5. Using photometric redshifts and spectral synthesis models, we have selected galaxy samples as a function of redshift, rest-frame color and luminosity. We selected samples with the same range of present-day rest-frame colors and luminosities so we could measure galaxy clustering as a function of redshift with comparable galaxy samples. We find the clustering of galaxies to be a weak function of rest-frame color and a strong function of luminosity. However, we do not detect significant evolution of the galaxy correlation function at z<1.5.
