The space density of cataclysmic variables: constraints from the ROSAT North Ecliptic Pole Survey
M. L. Pretorius, C. Knigge, D. O'Donoghue +3
We use the ROSAT North Ecliptic Pole (NEP) survey to construct a small, but purely X-ray flux-limited sample of cataclysmic variable stars (CVs). The sample includes only 4 systems…
High redshift X-ray galaxy clusters. I. The impact of point sources on the cluster properties
M. Branchesi, I. M. Gioia, C. Fanti +1
The current generation of X-ray observatories like Chandra allows studies with very fine spatial details. It is now possible to resolve X-ray point sources projected into the clust…
High redshift X-ray galaxy clusters. II. The L_X-T relationship revisited
M. Branchesi, I. M. Gioia, C. Fanti +1
In this paper we re-visit the observational relation between X-ray luminosity and temperature for high-z galaxy clusters and compare it with the local L_X-T and with theoretical mo…
The soft X-ray Cluster-AGN spatial 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…
