Evidence for Non-Hydrostatic Gas from the Cluster X-ray to Lensing Mass Ratio
A. Mahdavi, H. Hoekstra, A. Babul +1
Using a uniform analysis procedure, we measure spatially resolved weak gravitational lensing and hydrostatic X-ray masses for a sample of 18 clusters of galaxies. We find a radial…
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…
Robust quantitative measures of cluster X-ray morphology, and comparisons between cluster characteristics
Yasuhiro Hashimoto, Hans Boehringer, J. Patrick Henry +2
To investigate the relationships between dynamical status and other important characteristics of galaxy clusters, we conducted a study of X-ray cluster morphology using a sample of…
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…
Warm-Hot Intergalactic Medium Associated with the Coma Cluster
Yoh Takei, J. Patrick Henry, Alexis Finoguenov +4
We present our XMM-Newton RGS observations of X Comae, an AGN behind the Coma cluster. We detect absorption by NeIX and OVIII at the redshift of Coma with an equivalent width of 3.…
