Highredshift Clusters

Unfortunately, because of the limited resolution and collecting area of ROSAT it has been difficult to study the morphologies of distant clusters. Two of the best examples (z ~ 0.4) imaged with the ROSAT

HRI are displayed in Figure 3.10. The cluster RX J1347.5-1145 appears to be a relaxed, cooling flow (Schindler et al. 1997) while the cluster Cl 0024+17 may have substantial substructure as quantified by a center shift (Bohringer et al. 2000). These tantalizing glimpses demonstrate the need for a systematic study at high resolution with Chandra.
