Stellar Kinematics in the Complicated Inner Spheroid of M31: Discovery of Substructure along the Southeastern Minor Axis and Its Relationship to the Giant Southern Stream

We present the discovery of a kinematically cold stellar population along the southeastern minor axis of the Andromeda galaxy (M31) that is likely the forward continuation of M31's giant southern stream. This discovery was made during an on-going spectroscopic survey of M31 red giant branch (RG...
