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…

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…
