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…
The Extended Star Formation History of the Andromeda Spheroid at Twenty One Kiloparsecs on the Minor Axis
Thomas M. Brown, Ed Smith, Henry C. Ferguson +8
Using the HST ACS, we have obtained deep optical images of a southeast minor-axis field in the Andromeda Galaxy, 21 kpc from the nucleus. In both star counts and metallicity, this…
Discovery of Andromeda XIV: A Dwarf Spheroidal Dynamical Rogue in the Local Group?
Steven R. Majewski, Rachael L. Beaton, Richard J. Patterson +9
In the course of our survey of the outer halo of the Andromeda Galaxy we have discovered a remote, possible satellite of that system at a projected 162 kpc (11.7 degrees) radius. T…
