XMM-NEWTON STUDIES OF DLS SHEAR-SELECTED GALAXY CLUSTERS

We propose to study several massive Xray clusters identified in the Deep LensSurvey (DLS) from their weak lensing shear. The DLS is a deep multicolor (BVRz.)imaging survey of 28 square degrees being carried out at the 4m telescopes ofthe US National Observatories. The DLS shearselected cluster sample makes itpossible for the first time to study clusters in a baryonindependent way. Weare pursuing detailed investigations of this sample with HST and groundbasedKeck spectroscopy. The main goal of these XMMNewton observations is to measurethe intracluster gas temperatures of confirmed Xray clusters in the DLS. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
