Welcome to the Geha Research Group at Yale University in the Department of Astronomy. We are focused on understanding low mass galaxies around our Milky Way, in the Local Group and nearby Universe. Low mass galaxies provide significant constraints on galaxy formation processes, cosmology and the nature of dark matter. We study low mass galaxies ranging from gas-rich dwarf galaxies in isolation, to the least luminous and most dark matter-dominated galaxies in orbit around the Milky Way. The Geha group has weekly research meetings and welcomes postdocs, graduate and undergraduate students.
