XMM-Newton studies of a massive cluster of galaxies: RXCJ2228.6+2036

Understand

We present the X-ray properties of a massive cluster of galaxies (RXCJ2228.6+2036 at $z=0.421$) using {\it 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 ($r_{cool}=147\pm10$ kpc).
• The total cluster mass is $M_{500}=(1.19\pm0.35)\times10^{15}$ M$_{\odot}$ and the mean gas mass fraction is $f_{gas}=0.165\pm0.045$ at $r_{500}=1.61\pm0.16$ Mpc.
