Abstract/Description

The number of known strong galaxy-size gravitational lenses is increasing, as is the precision of measurements of lens properties, potentially allowing lensing to become a competitive tool for studying cosmology and the structure of galaxies. However, neglecting the environments of lenses creates biases and uncertainties in lensing results that limit their usefulness. I will present results from our survey of the environments and lines of sight of 28 strong gravitational lenses and discuss the applications of these results to lens knowledge. I will also describe how we are turning the problem around and using the poor groups of galaxies that we have discovered around lenses to study the evolution of group galaxies since z 0.6.
