Keck Week Video #10: The Milky Way’s Entourage – Dr. Marla Geha

This talk presents a new class of dark matter dominated small galaxies found in the neighborhood of our Milky Way Galaxy. Unlike the low luminosity of the objects she studies, Dr. Marla Geha from Yale University shines brightly in this talk describing research in action at the W. M. Keck Observatory.  
 
Revealed by the potent combination of two powerful astronomy tools, the Sloan Digital Sky Survey and the Keck II telescope’s DEIMOS instrument, these faint, ghost-like galaxies are amazing laboratories for simultaneously advancing science and raising new questions about the cosmos.
