The 3D soft X-ray cluster-AGN cross-correlation function in the ROSAT NEP survey
N. Cappelluti, H. Boehringer, P. Schuecker +4
X-ray surveys facilitate investigations of the environment of AGNs. Deep Chandra observations revealed that the AGNs source surface density rises near clusters of galaxies. The nat…
The 160 Square Degree ROSAT Survey - Revised Catalog & Cluster Evolution
Christopher Mullis, Brian McNamara, Hernan Quintana +6
We have constructed a large, statistically complete sample of galaxy clusters serendipitously detected as extended X-ray sources in 647 ROSAT PSPC pointed observations. The survey…
Cluster Surveys
Isabella M. GIOIA
I review some of the current efforts to create unbiased samples of galaxy clusters. Readers are referred elsewhere for general wide area sky surveys and redshift surveys, and for S…
Evolution of the cluster X-ray luminosity function from the WARPS survey
L. R. Jones, H. Ebeling, C. Scharf +5
The evolution of the X-ray luminosity function of clusters of galaxies has been measured to z=0.85 using over 150 X-ray selected clusters found in the WARPS survey. We find no evid…
A Cluster Deficit in the ROSAT NEP Survey
Isabella Gioia
We have used data from the deepest region of the ROSAT All-Sky Survey, the North Ecliptic Pole (NEP) region, to produce a complete and unbiased X-ray selected sample of distant clu…
Weak Lensing Observations of High-Redshift Clusters of Galaxies
D. Clowe, G. Luppino, N. Kaiser +1
We present results of a weak gravitational lensing survey of six X-ray selected high-redshift clusters of galaxies. We find that the masses of the clusters derived from weak lensin…
