  author={Howard K. C. Yee and Bau-Ching Hsieh and Huan Lin and Michael D. Gladders},
  journal={The Astrophysical Journal},
We analyze the B - RC colors of galaxies as functions of luminosity and local galaxy density using a large photometric redshift catalog based on the Red-Sequence Cluster Survey. We select two samples of galaxies with a magnitude limit of M < -18.5 and redshift ranges of 0.2 ≤ z < 0.4 and 0.4 ≤ z < 0.6 containing ~105 galaxies each. We model the color distributions of subsamples of galaxies and derive the red galaxy fraction and peak colors of red and blue galaxies as functions of galaxy… Expand
