The XMM Cluster Survey: Forecasting cosmological and cluster scaling-relation parameter constraints
Martin Sahlén, Pedro T. P. Viana, Andrew R. Liddle +16
We forecast the constraints on the values of sigma_8, Omega_m, and cluster scaling relation parameters which we expect to obtain from the XMM Cluster Survey (XCS). We assume a flat…
The luminosity -- halo-mass relation for brightest cluster galaxies
Sarah Brough, Warrick Couch, Chris Collins +2
We examine the central-galaxy luminosity -- host-halo mass relation for 54 Brightest Group Galaxies (BGGs) and 92 Brightest Cluster Galaxies (BCGs) at z<0.1 and present the first m…
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…
The 2dF Galaxy Redshift Survey: correlation with the ROSAT-ESO Flux Limited X-ray (REFLEX) galaxy cluster survey
Matt Hilton, Chris Collins, Roberto De Propris +25
The ROSAT-ESO Flux Limited X-ray (REFLEX) galaxy cluster survey and the 2dF Galaxy Redshift Survey (2dFGRS) respectively comprise the largest, homogeneous X-ray selected cluster ca…
The environmental dependence of galaxy colors in intermediate redshift X-ray-selected clusters
David A. Wake, Chris A. Collins, Robert C. Nichol +2
We present a wide-field imaging study of the colors of bright galaxies in 12 X-ray selected clusters and groups of galaxies at z ~ 0.3. The systems cover one of the largest ranges…
project: III. Gas mass fraction shape in high redshift clusters
Rachida Sadat, Alain Blanchard, Sebastien C. Vauclair +10
We study the gas mass fraction, behavior in project. The typical shape of high redshift galaxy clusters follows the global shape inf…
