Abstract:
We study the relation between the internal structure of early-type
galaxies and their environment using 70 strong gravitational lenses
from the SLACS Survey. The Sloan Digital Sky Survey (SDSS) database is
used to determine two measures of overdensity of galaxies around each
lens - the projected number density of galaxies inside the tenth
nearest neighbor (Σ10) and within a cone of radius 1h-1Mpc (D1).
Description:
A full description of the SLACS Survey and the selection process -
together with images of all the lenses discovered with the Advanced
Camera for Surveys (ACS) - is given in Papers I and V of this series
(Bolton et al. 2006ApJ...638..703B 2006ApJ...638..703B, 2008, Cat. J/ApJ/682/964; see also
