Scientific paper

Gravitational lenses represent the only sample of galaxies selected on the basis of mass rather than luminosity, and are therefore powerful tools for studying the early-type galaxy population at intermediate redshift. Vital to this effort is high quality HST photometry, which has now been obtained for several dozen lenses by the CfA-Arizona Space Telescope Lens Survey (CASTLeS). Here we apply the expanded optical database toward an improved analysis of the evolution of elliptical galaxies, the relationship between mass and light, and the fundamental plane.
