Global Properties of M31's Stellar Halo from the SPLASH Survey. I. Surface Brightness Profile
Karoline M. Gilbert, Puragra Guhathakurta, Rachael L. Beaton +10
We present the surface brightness profile of M31's stellar halo out to a projected radius of 175 kpc. The surface brightness estimates are based on confirmed samples of M31 red gia…
The SPLASH Survey: Spectroscopy of 15 M31 Dwarf Spheroidal Satellite Galaxies
Erik J. Tollerud, Rachael L. Beaton, Marla C. Geha +13
We present a resolved-star spectroscopic survey of 15 dwarf spheroidal (dSph) satellites of the Andromeda Galaxy (M31) as part of the Spectroscopic and Photometric Landscape of And…
The SPLASH Survey: Internal Kinematics, Chemical Abundances, and Masses of the Andromeda I, II, III, VII, X, and XIV dSphs
Jason S. Kalirai, Rachael L. Beaton, Marla C. Geha +7
We present new Keck/DEIMOS spectroscopic observations of hundreds of individual stars along the sightline to Andromeda's first three discovered dwarf spheroidal galaxies (dSphs) -…
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…
