Scientific paper

The Sagittarius dwarf galaxy and associated streams are an important dynamical system that can be used to probe the properties of our own Milky Way galaxy as well as to shed light on how galaxies cannibalize their smaller counterparts. We have made observations of both Horizontal Branch and Red Clump stars in the Southern Arm of the Sagittarius Stream using the Hydra instrument on the WIYN telescope at KPNO. We will present the kinematic properties and population ratios of stars in this area of the stream.
