Galaxy archaeology - The quest for ancient mergers
The hierarchical assembly of galaxies through mergers is a key channel of galaxy evolution in the ΛCDM cosmological model. Quantifying these ancient...
The last decade has seen an amazing transformation in our ideas about the central bulges of disk galaxies. We are probably only half-way through this change. In...
Galaxy Cluster Assembly: Cluster and Protocluster Populations
We study the formation of galaxy cluster-size dark matter halos (M > 1014.0 Msun) formed within a set of cosmological Lambda CDM N-body simulations, and track...
We perform a sample of N-body simulations of a minor merger between a Milky Way type galaxy and a satellite, which is density scaled version of the primary...
We perform N-body simulations of a minor merger between a Milky Way like galaxy and a disk-like satellite. In this set of collisionless runs we vary critical...
