The K Band Luminosity Function of High Redshift Clusters
S. C. Ellis, L. R. Jones
K band observations of the galaxy populations of three high redshift (z=0.8-1.0), X-ray selected, massive clusters are presented. The observations reach a depth of K = 21.5, corres…
An XMM and Chandra view of massive clusters of galaxies to z=1
L. R. Jones, B. J. Maughan, H. Ebeling +7
The X-ray properties of a sample of high redshift (z>0.6), massive clusters observed with XMM-Newton and Chandra are described, including two exceptional systems. One, at z=0.89, h…
The Evolution of Cluster Radio Galaxies at 0.5<z<1
Eric S. Perlman, Christopher Frye, Harald Ebeling +3
We are conducting a deep radio survey of a sample of 25 distant () clusters of galaxies. Here we present a progress report. So far 17 of 25 clusters have been observed, to…
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 X-ray evolution of clusters of galaxies to z=0.9
L. R. Jones, H. Ebeling, C. Scharf +6
The evolution of the X-ray luminosity function of clusters of galaxies has been measured to z=0.9 using over 150 X-ray selected clusters discovered in the WARPS survey. We find no…
Multi-wavelength observations of an evolved galaxy group: An endpoint of galaxy merging?
L. R. Jones, T. J. Ponman, Duncan A. Forbes
The group of galaxies RXJ1340.6+4018 has approximately the same bolometric X-ray luminosity as other bright galaxy groups and poor clusters such as the Virgo cluster. However, 70%…
