英文摘要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 (T(500) = 8.92(-1.32)(+1.78) keV) showing a cooling flow rate of 12.0(-12.0)(+56.0) M(circle dot) yr(-1) based on spectral fitting within the cooling flow radius (r(cool) = 147 +/- 10 kpc). The total cluster mass is M(500) = (1.19 +/- 0.35) x 10(15) M(circle dot) and the mean gas mass fraction is f(gas) = 0.165 +/- 0.045 at r(500) = 1.61 +/- 0.16 Mpc. 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.
