Scientific paper

The Deep Lens Survey (DLS) is a deep, multicolor (BVRz'), wide area, optical imaging survey that is producing a new sample of massive galaxy clusters, selected purely based on their weak lensing shear. The main goal of these XMM-Newton observations is to measure the intracluster gas temperatures of X-ray clusters in the DLS sample that we have identified using Chandra. The new observations will allow us to construct an X-ray luminosity-temperature correlation from the mass-selected DLS clusters for comparison with the known correlation from purely X-ray selected samples. This is a critical test of the fair sample hypothesis, which underlies several cosmological tests using galaxy clusters.
