Recent Chandra and Xmm Observations of Two Very Different Galaxy Clusters: Rbs797 and Cl 0939+4713
نویسندگان
چکیده
RBS797 and CL 0939+4713 are two intermediate red-shift clusters (z = 0.35 − 0.41). They have very different morphologies but both show surprisingly interesting structures. RBS797 looks relaxed, with an almost circular morphology; a CHANDRA observation of this cluster has revealed two deep depressions in the X-ray emission near the core. CL 0939+4713 has instead an irregular morphology with evident substructures which seem to be in the process of merging. Throughout this talk, if not otherwise stated, the errors are 90% confidence level.

XMM observation of the dynamically young galaxy cluster
We present an XMM observation of the distant galaxy cluster CL 0939+4713. The X-ray image shows pronounced substructure, with two main subclusters which have even some internal structure. This is an indication that the cluster is a dynamically young system. This conclusion is supported by the temperature distribution: a hot region is found between the two main subclusters indicating that they a...
متن کاملDiscovery of depressions in the X-ray emission of the distant galaxy cluster RBS797 in a CHANDRA observation
We present CHANDRA observations of the X-ray luminous, distant galaxy cluster RBS797 at z = 0.35. In the central region the X-ray emission shows two pronounced X-ray minima, which are located opposite to each other with respect to the cluster centre. These depressions suggest an interaction between the central radio galaxy and the intra-cluster medium, which would be the first detection in such...
متن کاملHubble Space Telescope Near-infrared and Optical Imaging of Faint Radio Sources in the Distant Cluster Cl0939+4713
We present deep Hubble Space Telescope NICMOS near-infrared and WFPC2 optical imaging of a small region in the core of the distant rich cluster Cl 0939+4713 (z = 0.41). We compare the optical and near-infrared morphologies of cluster members and find apparent small-scale optical structures within the galaxies which are absent in the near-infrared. We conclude that strong dust obscuration is a c...
متن کاملThe morphological segregation of galaxies in clusters . III . The distant cluster Cl 0939 + 4713 ( Abell 851 ) ⋆
We have performed an isophotal analysis of galaxies in the distant (z = 0.4) cluster Cl0939+4713 (Abell 851), using post-refurbished Hubble Space Telescope images. Morphological type estimates for the galaxies are given. A rigorous comparison of the properties of the types shows that early-type galaxies in Cl0939+4713 are, within the present statistical or systematic errors, indistinguishable f...
متن کاملDeep Xmm-newton and Chandra Observations of Clj1226.9+3332: a Detailed X-ray Mass Analysis of a Z = 0.89 Galaxy Cluster
Deep XMM-Newton and Chandra observations of ClJ1226.9+3332 at z = 0.89 have enabled the most detailed X-ray mass analysis of any such high-redshift galaxy cluster. The XMM-Newton temperature profile of the system shows no sign of central cooling, with a hot core and a radially declining profile. A temperature map shows asymmetry with a hot region that appears to be associated with a subclump of...
