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.

Here on Keck 2 the 1st of our 2 primary fields has just risen above the horizon, so we are busily collecting photons from distant galaxies.
Howdy! This is @rhaegal on Keck 2 with grad student Intae, searching for the most distant galaxies with deep spectroscopy on DEIMOS.
Tonight's schedule is LRIS-ADC on Keck 1 and DEIMOS on Keck 2 for our lucky observers from UCLA and NASA. Sun set 06:04:00pm rise 06:09:00am
