Linking dwarf galaxies to halo building blocks with the most metal-poor star in Sculptor
Anna Frebel, Evan Kirby, Joshua D. Simon
Current cosmological models indicate that the Milky Way's stellar halo was assembled from many smaller systems. Based on the apparent absence of the most metal-poor stars in presen…
Local Group Dwarf Elliptical Galaxies: II. Stellar Kinematics to Large Radii in NGC 147 and NGC 185
M. Geha, R. P. van der Marel, P. Guhathakurta +3
We present kinematic and metallicity profiles for the M31 dwarf elliptical (dE) satellite galaxies NGC 147 and NGC 185. The profiles represent the most extensive spectroscopic radi…
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) -…
The SPLASH Survey: A Spectroscopic Portrait of Andromeda's Giant Southern Stream
Karoline M. Gilbert, Puragra Guhathakurta, Priya Kollipara +6
The giant southern stream (GSS) is the most prominent tidal debris feature in M31's stellar halo. The GSS is composed of a relatively metal-rich, high surface-brightness "core" and…
Multi-Element Abundance Measurements from Medium-Resolution Spectra. I. The Sculptor Dwarf Spheroidal Galaxy
Evan N. Kirby, Puragra Guhathakurta, Michael Bolte +2
We present measurements of Fe, Mg, Si, Ca, and Ti abundances for 388 radial velocity member stars in the Sculptor dwarf spheroidal galaxy (dSph), a satellite of the Milky Way. This…
The Role of Dwarf Galaxies in Building Large Stellar Halos
Evan N. Kirby, Puragra Guhathakurta, James S. Bullock +10
The hierarchical theory of galaxy formation rests on the idea that smaller galactic structures merge to form the galaxies that we see today. The past decade has provided remarkable…
