Stellar Stream and Halo Structure in the Andromeda Galaxy From a Subaru/Hyper Suprime-Cam Survey
Yutaka Komiyama, Masashi Chiba, Mikito Tanaka +13
We present wide and deep photometry of the northwest part of the halo of the Andromeda galaxy (M31) using Hyper Suprime-Cam on the Subaru Telescope. The survey covers 9.2 deg…
Global Properties of M31's Stellar Halo from the SPLASH Survey: III. Measuring the Stellar Velocity Dispersion Profile
Karoline M. Gilbert, Erik Tollerud, Rachael L. Beaton +7
We present the velocity dispersion of red giant branch (RGB) stars in M31's halo, derived by modeling the line of sight velocity distribution of over 5000 stars in 50 fields spread…
Deep Subaru Hyper Suprime-Cam observations of Milky Way satellites Columba I and Triangulum II
Jeffrey L. Carlin, David J. Sand, Ricardo R. Munoz +9
We present deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way (MW): Columba I and Triangulum II. The color magnitude diagra…
Modelling chemical abundance distributions for dwarf galaxies in the Local Group: the impact of turbulent metal diffusion
Ivanna Escala, Andrew Wetzel, Evan N. Kirby +6
We investigate stellar metallicity distribution functions (MDFs), including Fe and -element abundances, in dwarf galaxies from the Feedback in Realistic Environments (FIRE) proj…
An investigation of the formation and line properties of MgH in 3D hydrodynamical model stellar atmospheres
Anders O. Thygesen, Evan N. Kirby, Andrew J. Gallagher +4
Studies of the isotopic composition of magnesium in cool stars have so far relied upon the use of one-dimensional (1D) model atmospheres. Since the isotopic ratios derived are base…
The binary fraction of stars in dwarf galaxies: the case of Leo II
Meghin Spencer, Mario Mateo, Matthew Walker +4
We combine precision radial velocity data from four different published works of the stars in the Leo II dwarf spheroidal galaxy. This yields a dataset that spans 19 years, has 14…
Triangulum II: Not Especially Dense After All
Evan N. Kirby, Judith G. Cohen, Joshua D. Simon +3
Among the Milky Way satellites discovered in the past three years, Triangulum II has presented the most difficulty in revealing its dynamical status. Kirby et al. (2015a) identifie…
