Abstract
We propose GMOS imaging and spectroscopy of the most massive lenses in a sample of 102 galaxy cluster lenses now being imaged by the Spitzer Space Telescope. This is by far the largest sample of galaxy luster strong lenses ever defined and studied in a homogenous fashion. These data will yield lensed source redshifts and multi-band images which are central to studying both the lensed sources (metallicities, SED fits and stellar masses) and the lenses via both arcs statistics and detailed properties of lensing clusters with lensing mass models. These GMOS data are a core component of an extensive follow-up study including both optical and IR spectroscopy, optical and near to mid-IR imaging, wide field imaging for weak lensing analyses, and Sunyaev-Zeldovich effect data at mm wavelengths.
