The simulation results of the merging cluster with an initial parameter of mass ratio of 3:1 in each epoch (0 Gyr, 1.4 Gyr, 1.9 Gyr, 2.3 Gyr, and 3.4 Gyr) provided by the Galaxy Cluster Merger Catalog (ZuHone et al. 2016, 2018). The initial impact parameter is set to 1000 kpc in the z-axis direction, and the two clusters approach each other by moving along the x-axis. From the left panel to the right panel: X-ray surface brightness observed from the +z-axis direction, the +y-axis direction, the projected temperature observed from the +z-axis direction, the +y-axis direction, and the projected regions of the ICM of the main cluster (PRI1) and subcluster (PRI2) from the +y-axis direction, respectively. The position of the BCG in each cluster is marked with blue and red crosses.
