The X-ray Morphology of the Lensing Galaxy Cluster Cl0024+17
H. Böhringer, G. Soucail, Y. Mellier +2
The paper reports the analysis of a very deep ROSAT HRI observation of the distant lensing cluster, CL0024+17. The morphology of the cluster is studied and the small core radius in…
Likelihood Filter for Cluster Detection
Peter Schuecker, Hans Böhringer
The likelihood filter for cluster detection introduced by Postman et al. is generalized by using standard procedures and models originally developed in the theory of point processe…
Results from the REFLEX Cluster Survey
H. Böhringer, L. Guzzo, C. A. Collins +11
Based on the ROSAT All-Sky Survey we have conducted a large redshift survey as an ESO key programme to identify and secure redshifts for the X-ray brightest clusters found in the s…
Multiwavelength Observations of a Seyfert 1 Galaxy Detected in ACO 3627
P. A. Woudt, R. C. Kraan-Korteweg, A. P. Fairall +3
ACO 3627 is a rich, nearby cluster of galaxies at the core of the Great Attractor. At the low galactic latitude of b = -7.2 the galactic extinction is significant. Nevertheless, it…
X-ray/Optical analysis of the cluster of galaxies Abell 1300: Indications of a post-merger at z = 0.31
L. Lemonon, M. Pierre, R. Hunstead +3
We present ROSAT PSPC and HRI observations of the distant cluster A1300 (z = 0.3071) in conjunction with optical data, to investigate the physics of the intra-cluster medium and th…
X-ray evolution in the ROSAT Brightest Cluster Sample
H. Ebeling, S. W. Allen, C. S. Crawford +5
We present the X-ray luminosity function (XLF) of the ROSAT Brightest Cluster Sample (BCS), an X-ray selected, flux limited sample of 172 clusters of galaxies at compil…
