The universal galaxy cluster pressure profile from a representative sample of nearby systems (REXCESS) and the Y-SZ-M-500 relation
We investigate the regularity of cluster pressure profiles with REXCESS, a representative sample of 33 local (z < 0.2) clusters drawn from the REFLEX catalogue and observed with XMM-Newton. The… Expand
The structural and scaling properties of nearby galaxy clusters. II. The M-T relation

- 10 February 2005
Using a sample of ten nearby ($z\lesssim 0.15$), relaxed galaxy clusters in the temperature range [2–9]$~\rm keV$, we have investigated the scaling relation between the mass at various density… Expand
XMM- Newton Observation of the Coma Galaxy Cluster : The temperature structure in the central region
- M. Arnaud, N. Aghanim, +23 authors Usa
- Physics
- 3 November 2000
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/EPIC/MOS and extracted… Expand

We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg^{2} patch of sky centered on RA 0 h, Dec.… Expand
A2163: AN EXCEPTIONALLY HOT CLUSTER OF GALAXIES
- M. Arnaud, J. Hughes, +4 authors Isamu Hatsukade
- Physics
- 10 May 1992
Extensive observations of A2163, both in the optical and X-ray bands, are reported. The cluster displays a high temperature, gas and total mass as well as a strong optical luminosity and a large… Expand
Weak Gravitational Lensing and X-Ray Analysis of Abell 2163
- G. Squires, D. M. Neumann, +5 authors D. Woods
- Physics
- 12 March 1996
We report on the detection of dark matter in the cluster of galaxies Abell 2163 using the weak gravitational distortion of background galaxies and an analysis of the X-ray emission from the cluster.… Expand
XMM-Newton observation of the distant (z=0.6}) galaxy cluster RX J1120.1+4318

- Physics
- 18 April 2002
We report on a 20 ks XMM observation of the distant cluster RX J1120.1+4318, discovered at z = 0.6 in the SHARC survey. The cluster has a regular spherical morphology, suggesting it is in a relaxed… Expand

- Physics
- 5 August 2005
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. I review our… Expand
The dark matter distribution in z ∼0.5 clusters of galaxies I. Determining scaling relations with weak lensing masses
- G. Foex, G. Soucail, E. Pointecouteau, M. Arnaud, M. Limousin, G. Pratt
- Physics
- 20 August 2012
The total mass of clusters of galaxies is a key parameter for studing massive halos. It relates to numerous gravitational and baryonic processes at play in the framework of large-scale structure… Expand
