The Astronomical Society of Greenwich will present Dr. Maria Geha speaking on “Dwarf Galaxies, Dark Matter and the Milky Way” on Sunday, March 11 at 3:30 p.m.
Geha, professor in the Astronomy Department at Yale University, will discuss 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.
The talk is co-sponsored by Greenwich Library and will be held in the Cole Auditorium, 101 West Putnam Ave. For more information, call 203-622 7900 or visit astrogreenwich.org
