The Butcher-Oemler Effect at Moderate Redshift
Anne J. Metevier, A. Kathy Romer, M. P. Ulmer
We present the results of Butcher-Oemler-style analysis of three moderate- redshift (0.1<z<0.2) clusters which have bimodal X-ray surface brightness profiles. We find that at least…
A Serendipitous Galaxy Cluster Survey with XMM: Expected Catalogue Properties and Scientific Applications
A. Kathy Romer, Pedro T. P. Viana, Andrew R. Liddle +1
This paper describes a serendipitous galaxy cluster survey that we plan to conduct with the XMM X-ray satellite. We have modeled the expected properties of such a survey for three…
Simulations Applied to the Bright SHARC XCLF: Results and Implications
M. P. Ulmer, C. Adami, R. Pildis +3
We have performed simulations of the effectiveness of the Serendipitous High-redshift Archival ROSAT Cluster (SHARC) survey for various model universes. We find, in agreement with…
A Turn-over in the Galaxy Luminosity Function of the Coma Cluster Core?
C. Adami, M. P. Ulmer, F. Durret +5
Our previous study of the faint end (R21.5) of the galaxy luminosity function (GLF) was based on spectroscopic data in a small region near the Coma cluster center. In this pr…
Spectroscopic Observations of Optically Selected Clusters of Galaxies from the Palomar Distant Cluster Survey
B. P. Holden, R. C. Nichol, A. K. Romer +4
We have conducted a redshift survey of sixteen cluster candidates from the Palomar Distant Cluster Survey (PDCS) to determine both the density of PDCS clusters and the accuracy of…
The Bright SHARC Survey: The Cluster Catalog
A. K Romer, R. C. Nichol, B. P. Holden +9
We present the Bright SHARC (Serendipitous High-Redshift Archival ROSAT Cluster) Survey, which is an objective search for serendipitously detected extended X-ray sources in 460 dee…
The Bright SHARC Survey: The X-ray Cluster Luminosity Function
R. C. Nichol, A. K. Romer, B. P. Holden +6
We present here initial results on the X-ray Cluster Luminosity Function (XCLF) from the Bright SHARC sample of distant X-ray clusters of galaxies. This sample is 97% complete in i…
