Abstract (from CDS):

A detailed analysis of XMM-Newton observations of ClJ0046.3+8530 (z= 0.624) is presented. The cluster has a moderate temperature (kT= 4.1±0.3 keV) and appears to be relaxed. Emission is detected at ≥3σ significance to a radius of 88 per cent of R200(the radius enclosing an overdensity of 200 times the critical density at z= 0.624) in a surface brightness profile. A temperature profile (extending to 0.7R200) and hardness ratio map show no significant departures from the global temperature, within the statistical limits of the data. The cluster bolometric X-ray luminosity is LX= (4.3±0.3)x1044 erg/s, and the total mass derived within R200, assuming isothermality and hydrostatic equilibrium, is M200= 3.0+0.6–0.5x 1014 M. The gas entropy measured at 0.1R200is compared with a sample of local systems, and found to be consistent with self-similar evolution with redshift. The metallicity, gas density profile slope and gas mass fraction are all consistent with those found in low-z clusters.
