We propose to continue our approved XMM program to obtain detailed X-ray spectral and structural data for distant, optically-selected clusters. These observations will allow us to place accurate constraints on the temperature, metallicity, and gas mass fraction in the intracluster medium of rich, optically-selected clusters at high redshift. The target clusters are the most well-studied systems at z greater than 0.7 in the optical/IR; thus, the addition of XMM data will enable us to probe the relationship between the X-ray and optical properties and their implications for galaxy and cluster evolution. Here, we propose to observe our most complex system, a four-way merger at z = 0.84. Our program provides an essential comparison sample to well-studied, X-ray-selected clusters at similar redshifts.
