More than two dozen galaxies have been discovered in orbit around our own Milky Way galaxy over the past decade. These "ultra-faint" galaxies are less luminous than any other known galaxy, and are several million times fainter than the Milky Way itself. The Milky Way's ultra-faint galaxies have emerged as the most dark matter-dominated galaxies in the known Universe. On October 12, Marla Geha, Professor of Astronomy and of Physics at Yale University, will discuss the most recently discovered ultra-faint galaxies and share first images of these systems from the James Webb Space Telescope.

Marla Geha is a professor and astrophysicist at Yale University. Her research is focused on understanding how the smallest known galaxies formed, and using these galaxies to understand the nature of dark matter and the underlying cosmology of the Universe. She obtained her B.S. in Applied and Engineering Physics from Cornell University and her PhD in Astrophysics from University of California Santa Cruz. She is on the executive board of the Warrior Scholar Project and runs the Research Experience for Veteran Undergraduates (REVU) summer research program. She has received various honors including an Alfred P. Sloan Research Fellowship, a John S. Guggenheim Fellowship and most recently was awarded the Dylan Hixon '88 Prize for teaching excellence in the natural sciences at Yale.
