Dr. Maria Geha, professor in the Astronomy Department at Yale University, will give a talk on how dwarf galaxies provide new insights on dark matter.
Nearly two dozen galaxies have been discovered in orbit around our own Milky Way galaxy over the past decade.
These newly discovered "ultra-faint' galaxies are less luminous than any other known galaxy, and are several million times fainter than the Milky Way itself.
These ultra-faint galaxies have emerged as the most dark matter-dominated galaxies in the known Universe. They are dramatically reshaping our understanding of galaxy formation and may hold the keys to deciphering the nature of dark matter.
This Astronomical Society of Greenwich event will be held in the Cole Auditorium of Greenwich Library on Sunday, March 11 at 3:30 PM.
