The first holistic view of minor mergers of galaxy clusters (2019)
Thesis
Sheardown, A. J. (2019). The first holistic view of minor mergers of galaxy clusters. (Thesis). University of Hull. Retrieved from https://hull-repository.worktribe.com/output/4221856

Utilising hydrodynamic + N-body simulations, we present the first holistic view of minor mergers of galaxy clusters. A minor merger describes the merging of a main cluster and a less massive subhalo, this could be a subcluster, group or an elliptical...

The M49 group, residing outside the virial radius of the Virgo cluster, is falling onto the cluster from the south. We report results from deep XMM-Newton mosaic observations of M49. Its hot gas temperature is 0.8 keV at the group center and rises to... Read More about Extended X-ray study of M49: The frontier of the Virgo cluster.

Close-up view of an ongoing merger between the NGC 4839 group and the Coma cluster - a post-merger scenario (2019)
Journal Article
