Talk title and abstract
Simulations of galaxy groups and galaxy clusters
Galaxy clusters grow by accreting galaxies, and cluster environments play an important role in the subsequent evolution of these galaxies, removing their gas and changing their morphologies. However, the environmental histories of galaxies are complex. Galaxies can be pre-processed by groups and cosmic filaments, and pass through multiple different environments over their lifetimes. In this talk I will summarise my research, which focuses on using hydrodynamical simulations to constrain the environmental histories of galaxies. I use simulations to study the prevalence of backsplash galaxies -- galaxies that previously experienced a cluster environment, but are not in a cluster now -- and how galaxy groups evolve nearby to clusters. I will also talk about how simulations can be used to better inform observations of clusters, to understand the contributions of different processes to galaxy evolution. Finally, I will briefly discuss astronomy outreach, and tell everyone why they should be doing lots of it.
