An HST Lensing Survey of X-ray Luminous Galaxy Clusters

Graham Smith, University of Durham, UK

We are conducting a lensing survey of 12 massive galaxy clusters at z~0.2 using the Hubble Space Telescope. This talk will summarise the background to our survey and present our results to date, including constraints on cluster dark matter profiles from radial arcs, and a search for gravitationally lensed EROs.
