We examine the relationship between environment and the luminosities, surface brightnesses, colors, and profile shapes of luminous galaxies in the Sloan Digital Sky Survey (SDSS). For the SDSS sample, galaxy color is the galaxy property most predictive of the local environment. Galaxy color and luminosity—measures of the star formation history—jointly comprise the most predictive pair of properties. At fixed luminosity and color, density is not closely related to surface brightness or to Sérsic index—measures of galaxy structure. In the text, we discuss what measurable residual relationships exist, generally finding that at red colors and fixed luminosity, the mean density decreases at the highest surface brightnesses and Sérsic indices. In general, these results suggest that the structural properties of galaxies are less closely related to galaxy environment than are their masses and star formation histories.

Halo Occupation Statistics (2007, methodology): “…of all galaxies are based on the standard SDSS Petrosian technique (Petrosian 1976; Strauss et al. 2002), have been corrected for galactic extinction (Schlegel et al. 1998), and have beenK-corrected and evolution-corrected to z ¼ 0:1, using the method described in Blanton et al.
