The ROSAT-ESO Flux Limited X-Ray (REFLEX) Galaxy Cluster Survey I: The Construction of the Cluster Sample
H. Boehringer, P. Schuecker, L. Guzzo +10
We describe the construction of an X-ray flux-limited sample of galaxy clusters, the REFLEX survey catalogue, to be used for cosmological studies. The survey is based on the ROSAT…
The ROSAT-ESO Flux-Limited X-Ray (REFLEX) Galaxy Cluster Survey III: The Power Spectrum
Peter Schuecker, Hans Boehringer, Luigi Guzzo +11
We present a measure of the power spectrum on scales from 15 to 800 Mpc/h using the ROSAT-ESO Flux-Limited X-Ray(REFLEX) galaxy cluster catalogue. The REFLEX survey provides a samp…
The ROSAT-ESO Flux Limited X-ray (REFLEX) Galaxy Cluster Survey II: The Spatial Correlation Function
C. A. Collins, L. Guzzo, H. Boehringer +9
We report the results of the spatial two-point correlation function xi(r) for the new X-ray galaxy cluster survey REFLEX, which comprises of 452 X-ray selected clusters (449 with r…
BeppoSAX - ROSAT PSPC observations of the Shapley Supercluster: A3562
S. Ettori, S. Bardelli, S. De Grandi +3
We present a combined analysis of the BeppoSAX and ROSAT PSPC observation of the cluster of galaxies A3562, a massive member of the core of the Shapley Supercluster. With a complex…
Hard X-ray emission from the galaxy cluster A2256
R. Fusco-Femiano, D. Dal Fiume, S. De Grandi +6
After the positive detection by BeppoSAX of hard X-ray radiation up to ~80 keV in the Coma cluster spectrum, we present evidence for nonthermal emission from A2256 in excess of the…
Interaction in Abell 2256: the BeppoSAX view
Silvano Molendi, Sabrina De Grandi, Roberto Fusco-Femiano
We present results from a spatially resolved spectral analysis of the merging cluster Abell 2256. The long integration time (135 ks) and the good spatial resolution of the MECS onb…
