Scientific paper

We propose a 50ksec ACIS-I observation of the luminous, relaxed, cooling flow cluster ZW3146 at z=0.291 to determine accurate gas temperature, gas density, and heavy element abundance distributions to large radial distances. The X-ray observations will be supplemented with SZ effect and optical weak lensing observations. Together, these observations will constrain cosmological cluster models, test the validity of the universal temperature profile to higher redshift, determine the importance of non-thermal pressure support for the X-ray gas, measure iron abundance distributions and the iron mass in the cluster, detect small scale structure in the cooling core, and determine the radial dependence of the mass deposition rate in the cooling flow.
