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…
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…
XMM-Newton observations of three poor clusters: Similarity in dark matter and entropy profiles down to low mass
G. W. Pratt, M. Arnaud
(Abridged) We present an analysis of the mass and entropy profiles of three poor clusters (A1991, A2717 and MKW9) observed with XMM-Newton. The clusters have similar temperatures (…
Structural and scaling properties of galaxy clusters: probing the physics of structure formation
M. Arnaud, G. W. Pratt, E. Pointecouteau
We present XMM-Newton studies of the total mass, gas density, temperature and entropy profiles in nearby hot and cool clusters, together with follow-up observations of distant clus…
