OIR Research: Century Survey Galactic Halo Project
 

The Century Survey Galactic Halo Project uses evolved stars as luminous tracers of the outer parts of the Milky Way. The goal is to directly test the merger picture of Galaxy formation: the remnants of past mergers should still be visible as streams of stars moving together in the outer parts of the Milky Way. We measure the stars' velocities with the Whipple 1.5m telescope, and use those measurements to study the velocity structure of the Milky Way halo.
