Taking the Measure of the Universe: Precision Astrometry with SIM PlanetQuest
Stephen C. Unwin, Michael Shao, Angelle M. Tanner +33
Precision astrometry at microarcsecond accuracy has application to a wide range of astrophysical problems. This paper is a study of the science questions that can be addressed usin…
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…
A Deep Proper-Motion Survey in Kapteyn Selected Areas: I. Survey Description and First Results for Stars in the Tidal Tail of Sagittarius and in the Monoceros Ring
Dana I. Casetti-Dinescu, Steven R. Majewski, Terrence M. Girard +4
We describe a high-precision, deep (to V ~ 19-21) absolute proper-motion survey that samples ~50 lines of sight in the Kapteyn Selected Areas along declination zones -15, 0 and 15…
Unveiling the Boxy Bulge and Bar of the Andromeda Spiral Galaxy
Rachael L. Beaton, Steven R. Majewski, Puragra Guhathakurta +6
A new, 2.8 deg^2 J,H,K_s infrared survey from the 2MASS 6x program across the extent of the optical disk of the Andromeda (M31) galaxy provides a clear view of the M31 center almos…
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…
Exploring Halo Substructure with Giant Stars XI: The Tidal Tails of the Carina Dwarf Spheroidal and the Discovery of Magellanic Cloud Stars in the Carina Foreground
Ricardo R. Munoz, Steven R. Majewski, Simone Zaggia +10
A new large-area Washington M,T_2+DDO51 filter survey of more than 10 deg^2 around the Carina dSph galaxy reveals a spectroscopically confirmed power law radial density "break" pop…
