Abstract
AbstractWe have undertaken the DAFT/FADA survey with the double aim of setting constraints on dark energy based on weak lensing tomography and of obtaining homogeneous and high quality data for a sample of 91 massive clusters in the redshift range 0.4–0.9 for which there were HST archive data. We have analysed the XMM‐Newton data available for 42 of these clusters to derive their X‐ray temperatures and luminosities and search for substructures. Out of these, a spatial analysis was possible for 30 clusters, but only 23 had deep enough X‐ray data for a really robust analysis. This study was coupled with a dynamical analysis for the 26 clusters having at least 30 spectroscopic galaxy redshifts in the cluster range. Altogether, the X‐ray sample of 23 clusters and the optical sample of 26 clusters have 14 clusters in common. We present preliminary results on the coupled X‐ray and dynamical analyses of these 14 clusters. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
