Chandra observation of the multiple merger cluster Abell 521
C. Ferrari, M. Arnaud, S. Ettori +2
We present the Chandra analysis of the galaxy cluster A521 (z=0.247). The high resolution of the Chandra observation has allowed us to refine the original merging scenario proposed…
X-ray observations of Clusters of Galaxies
M. Arnaud
X-ray observations of clusters provide key information on the dark matter, on the formation of structures in the Universe, and can be used to constrain the cosmological parameters.…
Probing the dark matter profile of hot clusters and the M-T relation with XMM-Newton
E. Pointecouteau, M. Arnaud, G. W. Pratt
We present results based on XMM-Newton observations of a small sample of hot galaxy clusters. Making a full use of XMM-Newton's spectro-imaging capabilities, we have extracted the…
The structural and scaling properties of nearby galaxy clusters - II. The M-T relation
M. Arnaud, E. Pointecouteau, G. W. Pratt
Using a sample of ten nearby (z< 0.15), relaxed galaxy clusters in the temperature range [2-9] keV, we have investigated the scaling relation between the mass at various density co…
The structural and scaling properties of nearby galaxy clusters: I - The universal mass profile
E. Pointecouteau, M. Arnaud, G. W. Pratt
We present the integrated mass profiles for a sample of ten nearby (z<=0.15), relaxed galaxy clusters, covering a temperature range of [2-9]keV, observed with XMM-Newton. The mass…
