Relating the Diverse Merger Histories and Satellite Populations of Nearby Galaxies

Event Information:

The hierarchical formation of galaxies like the Milky Way (MW) is a central prediction of the Lambda-Cold Dark Matter (LCDM) model. They are predicted and observed to host vast halos of stars accreted from disrupted dwarf galaxies, as well as rich dwarf satellite populations — both of which tantalizingly encode details of their formation histories. This regime has long been problematic for galaxy formation models, due to the required resolution, and observational progress has been largely constrained to the Local Group, due to the intrinsic faintness and large scales of both features.
