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…
The Far Ultraviolet Spectroscopic picture of the Missing Baryons in the Local Group
F. Nicastro, A. Zezas, M. Elvis +6
The number of detected baryons in the low-redshift Universe (z < 1) is far small er than the corresponding number of baryons observed at higher redshift. According to hydrodynamica…
The Butcher-Oemler Effect in High Redshift X-ray Selected Clusters
David A. Wake, Chris A. Collins, Bruce W. Fairley +4
We are engaged in a wide-field, multi-colour imaging survey of X-ray selected clusters at intermediate and high redshift. We present blue fractions for the first 8 out of 29 cluste…
The Properties of Brightest Cluster Galaxies in X-Ray Selected Clusters
Sarah Brough, Chris A. Collins, Doug J. Burke +2
We present the K-band Hubble diagram for 162 brightest cluster galaxies (BCGs) in X-ray selected clusters, 0.01<z<0.83. The sample incorporates that of Burke, Collins, & Mann (2000…
The XMM-Newton Project
J. G. Bartlett, N. Aghanim, M. Arnaud +16
The abundance of high-redshift galaxy clusters depends sensitively on the matter density $\OmM$ and, to a lesser extent, on the cosmological constant . Measurements of this abun…
The Southern SHARC Survey: the z = 0.3 - 0.7 Cluster XLF
D. J. Burke, C. A. Collins, R. M. Sharples +3
We present the z = 0.3 - 0.7 cluster X-ray luminosity function (XLF) determined from the Southern SHARC (Serendipitous High-redshift Archival ROSAT Cluster) survey. Over the lumino…
