Abstract (from CDS):

We present the X-ray properties of a massive cluster of galaxies (RXC J2228.6+2036 at z=0.421) using XMM-Newton data. The X-ray mass modeling is based on the temperature and density distributions of the intracluster medium derived using a deprojection method. We find that RXC J2228.6+2036 is a hot cluster (T500=8.92+1.78–1.32keV) showing a cooling flow rate of 12.0+56.0–12.0M/yr based on spectral fitting within the cooling flow radius (rcool=147±10kpc). The total cluster mass is M500=(1.19±0.35)x1015M and the mean gas mass fraction is fgas=0.165±0.045 at r500=1.61±0.16Mpc. We discuss the PSF-correction effect on the spectral analysis and find that, for the selected annular width, the PSF-corrected temperatures are consistent with those without PSF-correction. We observe remarkable agreement between X-ray and SZ results, which is of prime importance for future SZ surveys. RXC J2228.6+2036 obeys the empirical scaling relations found in general massive galaxy clusters (e.g. S-T, M-T, L-T and M-Y), after accounting for self-similar evolution.
