Kinematic and Chemical constraints on the formation of M31's inner and outer halo
A. Koch, R. M. Rich, D. B. Reitzel +8
The halo of M31 shows a wealth of substructures that are consistent with satellite accretion. Here we report on kinematic and abundance results from Keck/DEIMOS spectroscopy in the…
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
Karoline M. Gilbert, Mark Fardal, Jasonjot S. Kalirai +9
We present the discovery of a kinematically-cold stellar population along the SE minor axis of the Andromeda galaxy (M31) that is likely the forward continuation of M31's giant sou…
Exploring Halo Substructure with Giant Stars X. Extended Dark Matter or Tidal Disruption?: The Case for the Leo I Dwarf Spheroidal Galaxy
Sangmo Tony Sohn, S. R. Majewski, R. R. Muñoz +7
We present a wide-field (4.5 deg^2) photometric and spectroscopic survey of the Leo I dwarf spheroidal (dSph) galaxy to explore its extended morphology and dynamics. As in previous…
The Metal-Poor Halo of the Andromeda Spiral Galaxy (M31)
J. S. Kalirai, K. M. Gilbert, P. Guhathakurta +6
We present spectroscopic observations of red giant branch (RGB) stars over a large expanse in the halo of the Andromeda spiral galaxy (M31), acquired with the DEIMOS instrument on…
Discovery of an Extended Halo of Metal-poor Stars in the Andromeda Spiral Galaxy

A New Method for Isolating M31 Red Giant Stars: The Discovery of Stars out to a Radial Distance of 165 Kiloparsecs
Karoline M. Gilbert, Puragra Guhathakurta, Jasonjot S. Kalirai +8
We present a method for isolating a clean sample of red giant stars in the outerregions of the Andromeda spiral galaxy (M31) from an ongoing spectroscopic survey using the DEIMOS i…
