The Steepness Ratio Technique: A New Method to analyze ROSAT All-Sky Survey Extended Sources (1997)
De Grandi, S., Molendi, S., Böhringer, H., Chincarini, G., Voges, W.
In this first paper of a series we develop a new technique to analyze clusters of galaxies observed during the ROSAT All-Sky Survey (RASS). We call this method the Steepness Ratio Technique (SRT)....
Kull, A., Treumann, R. A., Böhringer, H.
The statistical mechanical investigation of violent relaxation (Lynden-Bell 1967) is extended to indistinguishable objects. It is found that, coincidentally, the equilibrium distribution is the same...
A Weak Gravitational Lensing and X-ray Analysis of Abell 2163 (1996)
Squires, G., Neumann, D. M., Kaiser, N., Arnaud, M., Babul, A., Böhringer, H., ...
We report on the detection of dark matter in the cluster of galaxies Abell~2163 using the weak gravitational distortion of background galaxies, and an analysis of the cluster X-ray emission. We find...
ROSAT/HRI and ASCA observations of the most luminous X-ray cluster RXJ1347.5-1145 (1996)
Schindler, S., Hattori, M., Neumann, D. M., Böhringer, H.
We report on the X-ray properties of the exceptional X-ray cluster RXJ1347.5-1145 at z=0.451. We confirm that it is with a luminosity $L_X(bol)=2\times 10^{46}$ erg/s the most luminous X-ray cluster...
Nyman, L. A. A., Lemke, R., Böhringer, H., Shaver, P. A., Martinis, L., Pizzo, L., ...
Abstract: An observing campaign was devoted to the search for the Sunyaev-Zeldovich (S-Z) effect towards X-ray ROSAT Clusters in the millimetric spectral domain. A double channel (1.2 and 2 {it mm})...
ROSAT/GINGA observation of the galaxy cluster A3921 (1996)

X-ray evolution in the ROSAT Brightest Cluster Sample (1995)
Ebeling, H., Allen, S. W., Crawford, C. S., Edge, A. C., Fabian, A. C., Böhringer, H., ...
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 $z\leq 0.3$ compiled from ROSAT...
Squires, G., Kaiser, N., Babul, A., Fahlman, G., Woods, D., Neumann, D. M., ...
We report on the detection of dark matter in the cluster Abell 2218 using the weak gravitational distortion of background galaxies. We find a highly significant, coherent detection of the distortion...
Discovery of an Arc System in the Brightest ROSAT Cluster of Galaxies (1995)
Schindler, S., Guzzo, L., Ebeling, H., Böhringer, H., Chincarini, G., Collins, C. A., ...
We report the discovery of two bright arcs in what turns out to be the brightest X--ray cluster in the ROSAT band ever observed, RXJ1347.5-1145. Its luminosity is $(6.2\pm0.6) \cdot10^{45}$erg...
