Clusters of galaxies are known to be dynamically active systems, yet X-ray studies of the low-redshift population exhibit tight scaling laws. In this work, we extend previous studies of this apparent paradox using numerical simulations of two extreme merger cases, one is a high Mach number (above 2.5) satellite merger similar to the "bullet cluster" and the other is a merger of nearly equal-mass progenitors. Creating X-ray images densely sampled in time, we construct TX, Mgas, and YX measures… Expand
