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…
XMM- Newton Observation of the Coma Galaxy Cluster: The temperature structure in the central region
M. Arnaud, N. Aghanim, R. Gastaud +8
We present a temperature map and a temperature profile of the central part (r < 20' or 1/4 virial radius) of the Coma cluster. We combined 5 overlapping pointings made with XMM/EPI…
The NGC4839 group falling into the Coma cluster observed by XMM-Newton
D. M. Neumann, M. Arnaud, R. Gastaud +7
We present here the first analysis of the XMM Newton EPIC-MOS data of the galaxy group around NGC4839, which lies at a projected distance to the Coma cluster center of 1.6Mpc. In o…
Optical follow-up of the REFLEX survey: a new perspective in cluster studies
L. T. Barone, E. Molinari, H. Boehringer +8
After the completion of the catalogue built with ESO key program (REFLEX), we are beginning to explore the multiband optical characteristics of a subsample of those clusters select…
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…
Is MS1054-03 an exceptional cluster? A new investigation of ROSAT/HRI X-ray data
D. M. Neumann, M. Arnaud
We reanalyzed the ROSAT/HRI observation of MS1054-03, optimizing the channel HRI selection and including a new exposure of 68 ksec. From a wavelet analysis of the HRI image we iden…
