Resilience of sloshing cold fronts against subsequent minor mergers

Minor mergers are common in galaxy clusters. They have the potential to create sloshing cold fronts (SCFs) intracluster medium (ICM) of cluster. However, resilience SCFs subsequent minor is unknown. Here we investigate extent which established by an off-axis merger disrupted a merger. We perform suite 13 hydrodynamic + N-body simulations idealised triple cluster vary approach direction and impact parameter tertiary Except for ~1 Gyr after first core passage cluster, clear present all configurations. Subsequent head-on reduce number significantly, while only moderately SCFs. In particular, outer (>~500 kpc) resilient. The results this work indicate that easily formed course long-lived even if further takes place. thus should be ubiquitous, but deriving history given based on its observed might more complex than previously thought.
