Galaxy cluster X-ray luminosity scaling relations from a representative local sample (REXCESS)
G. W. Pratt, J. H. Croston, M. Arnaud +1
(Abridged) We examine the X-ray luminosity scaling relations of 31 nearby galaxy clusters from the Representative XMM-Newton Cluster Structure Survey (REXCESS). The objects are sel…
Galaxy-cluster gas-density distributions of the Representative XMM-Newton Cluster Structure Survey (REXCESS)
J. H. Croston, G. W. Pratt, H. Boehringer +7
We present a study of the structural and scaling properties of the gas distributions in the intracluster medium (ICM) of 31 nearby (z < 0.2) clusters observed with XMM-Newton, whic…
A2163: Merger events in the hottest Abell galaxy cluster I. Dynamical analysis from optical data
S. Maurogordato, A. Cappi, C. Ferrari +7
We present a detailed optical analysis of the galaxy cluster A2163 based on new multicolor wide field imaging and medium-to-high resolution (R~2000) spectroscopy. While X-ray obser…
The Representative XMM-Newton Cluster Structure Survey (REXCESS) of an X-ray Luminosity Selected Galaxy Cluster Sample
H. Boehringer, P. Schuecker, G. W. Pratt +31
The largest uncertainty for cosmological studies using clusters of galaxies is introduced by our limited knowledge of the statistics of galaxy cluster structure, and of the scaling…
XMM-Newton observations of the eastern jet of SS433
W. Brinkmann, G. W. Pratt, S. Rohr +2
The radio supernova remnant W50 hosts at its center the peculiar galactic X-ray binary SS 433. It shows a central spherical structure with two `ears' which are supposed to be forme…
Temperature profiles of a representative sample of nearby X-ray galaxy clusters
G. W. Pratt, H. Boehringer, J. H. Croston +4
A study of the structural and scaling properties of the temperature distribution of the hot, X-ray emitting intra-cluster medium of galaxy clusters, and its dependence on dynamical…
