Clusters of galaxies are dominated by dark matter. In mergers between massive clusters, the positions of the dark matter and main baryonic components can become separated. In rare cases, it is possible to study the presence of these two components independently. Here we propose to observe a spectacular example of such a system: the extraodinary, high-redshift cluster MACSJ0025.4-1222. Detailed Hubble Space Telescope and Subaru optical data for this system are in hand, and gravitational lensing shows the dominance of dark matter. There remains however one missing link: a detailed mass map of the main baryonic component, the hot X-ray emitting gas. We propose a deep observation to address this issue, and also to produce detailed maps of the thermodynamic state of this unique cluster.
