Resilience of sloshing cold fronts against subsequent minor mergers. Monthly notices of the Royal Astronomical Society, 514(1), 518-534. https://doi.org/10.1093/mnras/stac784

Minor mergers are common in galaxy clusters. They have the potential to create sloshing cold fronts (SCFs) in the intracluster medium of the cluster. However, the resilience of SCFs to subsequent minor mergers is unknown. Here we investigate the exte... Read More about Resilience of sloshing cold fronts against subsequent minor mergers.
