Stellar and total baryon mass fractions in groups and clusters since redshift 1
S. Giodini, D. Pierini, A. Finoguenov +24
We investigate if the discrepancy between estimates of the total baryon mass fraction obtained from observations of the cosmic microwave background (CMB) and of galaxy groups/clust…
The Evolution of Galaxy Clusters Across Cosmic Time
M. Arnaud, H. Bohringer, C. Jones +40
The large scale structure of the present Universe is determined by the growth of dark matter density fluctuations and by the dynamical action of dark energy and dark matter. While…
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…
