Dwarf Galaxies and Near Field Cosmology

Welcome the Geha Research Group at Yale University.   This research page serves as a repository for current members, affiliates, and students interested in joining the group.

Research Summary:    Dwarf galaxies are the dominate type of galaxy in the Universe by number.  Dwarf galaxies are less luminous and more dark-matter dominated as compared to our Milky Way, providing significant constraints on galaxy formation processes, cosmology and the nature of dark matter.  We are focused on understanding dwarf galaxies around our Milky Way, Local Group and nearby Universe.
