A detailed analysis of XMM observations of ClJ0046.3+8530 (z=0.624) is presented. The cluster has a moderate temperature (kT=4.1+/-0.3keV) and appears to be relaxed. Emission is detected at >3 sigma significance to a radius of 88% 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 clusters bolometric X-ray luminosity is L=(4.3+/-0.3)*10^44 erg/s, and the total mass derived within R200, assuming isothermality and hydrostatic equilibrium, is M_200=3.0^{+0.6}_{-0.5}*10^14 Msolar. The gas entropy measured at 0.1R200 is 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.
A detailed X-ray analysis of an XMM-Newton observation of the high-redshift (z=0.89) galaxy cluster ClJ1226.9+3332 is presented. The X-ray temperature is found to be 11.5{+1.1}{-0.9}keV, the highest X-ray temperature of any cluster at z>0.6. In contr
We present the results of XMM-Newton observations of three high-redshift powerful radio galaxies 3C 184, 3C 292 and 3C 322. Although none of the sources lies in as rich an X-ray-emitting environment as is seen for some powerful radio galaxies at low
We present results on the physical states of three high-redshift powerful radio galaxies (3C 292 at z=0.7, 3C 184 at z=1, and 3C322 at z=1.7). They were obtained by combining radio measurements with X-ray measurements from XMM-Newton that separate sp
We studied the intracluster medium of the galaxy cluster CIZA J2242.8+5301 using deep XMM-Newton observations. The cluster hosts a remarkable 2-Mpc long, ~50-kpc wide radio relic that has been nicknamed the Sausage. A smaller, more irregular counter-
We present an analysis of deep XMM-Newton and Chandra observations of the z=1.05 galaxy cluster XLSSJ022403.9-041328 (hereafter XLSSC 029), detected in the XMM-Newton large scale structure survey. Density and temperature profiles of the X-ray emittin
