Are fossil groups a challenge of the Cold Dark Matter paradigm?
Stefano Zibetti, Daniele Pierini, Gabriel W. Pratt
We study six groups and clusters of galaxies suggested in the literature to be `fossil' systems (i.e. to have luminous diffuse X-ray emission and a magnitude gap of at least 2 mag-…
A2163: Merger events in the hottest Abell galaxy cluster I. Dynamical analysis from optical data
S. Maurogordato, A. Cappi, C. Ferrari +7
We present a detailed optical analysis of the galaxy cluster A2163 based on new multicolor wide field imaging and medium-to-high resolution (R~2000) spectroscopy. While X-ray obser…
Calibration of the galaxy cluster M_500-Y_X relation with XMM-Newton
M. Arnaud, E. Pointecouteau, G. W. Pratt
The quantity Y_ X, the product of the X-ray temperature T_ X and gas mass M_ g, has recently been proposed as a robust low-scatter mass indicator for galaxy clusters. Using precise…
Temperature profiles of a representative sample of nearby X-ray galaxy clusters
G. W. Pratt, H. Boehringer, J. H. Croston +4
A study of the structural and scaling properties of the temperature distribution of the hot, X-ray emitting intra-cluster medium of galaxy clusters, and its dependence on dynamical…
