	OIR Research: Century Survey Galactic Halo Project

	The Century Survey Galactic Halo Project uses luminous "blue horizontal-branch" stars to map the outskirts of the Milky Way halo. We measure the stars' velocities and search for star streams from past galaxy mergers. The goal is to directly test the merger picture of Galaxy formation.
