We present the X-ray properties of a massive cluster of galaxies ( RXCJ2228.6+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 found that RXCJ2228.6+2036 is a hot cluster ( T _ { 500 } = 8.92 ^ { +1.78 } _ { -1.32 } keV ) showing a cooling flow rate of 12.0 ^ { +56.0 } _ { -12.0 } M _ { \odot } yr ^ { -1 } based on spectral fitting within the cooling flow radius ( r _ { cool } = 147 \pm 10 kpc ) .
The total cluster mass is M _ { 500 } = ( 1.19 \pm 0.35 ) \times 10 ^ { 15 } M _ { \odot } and the mean gas mass fraction is f _ { gas } = 0.165 \pm 0.045 at r _ { 500 } = 1.61 \pm 0.16 Mpc .
We discussed the PSF-correction effect on the spectral analysis and found that for the annular width we chose the PSF-corrected temperatures are consistent with those without PSF-correction .
We observed a remarkable agreement between X-ray and SZ results , which is of prime importance for the future SZ survey .
RXCJ2228.6+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 .
