THE SPLASH SURVEY: A SPECTROSCOPIC PORTRAIT OF ANDROMEDA’S GIANT SOUTHERN STREAM
The giant southern stream (GSS) is the most prominent tidal debris feature in M31's stellar halo and covers a significant fraction of its southern quadrant. The GSS is a complex structure composed of a relatively metal-rich, high-surface-brightness "core" and a lower metallicity, lower-surface-brightness "envelope." We present spectroscopy of red giant …
