Numerical study of star cluster formation and evolution
Hui Li is trying to understand the globular cluster (GC) formation history in early-type galaxies, especially to explain the mystery of the bimodal metallicity distribution of GCs. By incorporating the mass-assembly history of dark matter halos extracted from the state-of-the-art Millennium-II N-body simulation, Li and his advisor are building up the merger trees of halos of different masses and constructing a semi-analytical model in the cosmological framework to trace the formation and evolution of GC properties – such as mass, age, and metallicity – within host halos. Statistical methods are used to compare our modeled GC populations to the observed ones in Virgo Cluster galaxies in ACSVCS in order to constrain the physical conditions of the GC formation process. Li hopes to reveal the physics behind the GC metallicity distribution and understand the chemical enrichment history of host galaxies.
