It is now well accepted that dark matter halos evolve in a hierarchical fashion. Every halo, and presumably the galaxy it hosts, begins as a small perturbation and grows via a complex and varied merger history. This poster presentation outlines efforts to use numerical simulations to better understand how galaxies are shaped by their past mergers. These studies naturally predict that galaxy mergers trigger starbursts, quasars, and leave behind remnants that resemble elliptical galaxies. This entire process is summarized in our Proposed Chronology of a Galaxy Merger and described in more detail in an accompanying set of papers.
