Abstract:
Globular clusters (GCs) are ancient, metal-poor objects that were traditionally thought to form and evolve in isolation. However, recent observations have revealed a surprising correlation between the total mass of GC systems and the mass assembly and metal enrichment history of their host galaxies. In this talk, I will present a series of investigations into the co-evolution of GCs and their host galaxies within the framework of hierarchical structure formation and various scaling relations. Specifically, I will discuss the mechanisms underlying the formation and evolution of GCs in relation to their host galaxies, as well as the implications of these findings for our understanding of galaxy evolution. If time permits, I will also discuss a special type of cluster, the nuclear star cluster, and its possible origins and observational signatures.
