Galactic Archaeology with the Subaru `Ånohi`ula Prime Focus Spectrograph Strategic Program
Masashi Chiba, Rosemary F. G. Wyse, Evan N. Kirby +47
The recently commissioned Subaru `Ånohi`ula Prime Focus Spectrograph (PFS) will obtain spectra from nearly 2,400 fibers that cover 1.24 square degrees. The 360 night Subaru Strate…
Scylla at APOGEE: The Impact of Starbursts on the Chemical Evolution of the Magellanic Clouds
Ivanna Escala, Kristen B. W. McQuinn, Sten Hasselquist +11
Owing to their proximity to the Milky Way, the Large and Small Magellanic Clouds (L/SMC) uniquely probe the evolution of low-mass galaxies undergoing mutual interactions. In this w…
A Chemodynamical Census of the Milky Way's Ultra-Faint Compact Satellites. I. A First Population-Level Look at the Internal Kinematics and Metallicities of 19 Extremely-Low-Mass Halo Stellar Systems
William Cerny, Ting S. Li, Andrew B. Pace +13
Deep, wide-area photometric surveys have uncovered a population of compact ( 1-15 pc), extremely-low-mass ( 20-4000 ) stellar systems in th…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
Kinematical Modeling of the Resolved Stellar Outskirts of M32: Constraints on Tidal Stripping Scenarios
Ivanna Escala, Douglas Grion Filho, Puragra Guhathakurta +8
As the only compact elliptical close enough to resolve into individual stars, the satellite dwarf galaxy M32 provides a unique opportunity for exploring the origins of such rare ga…
The M31-M33 Interaction: Impact on M31's Center of Mass Motion and Satellite Orbits
Ekta Patel, Nicolas Garavito-Camargo, Ivanna Escala
Inspired by recent studies of the Milky Way--LMC interaction and its implications for the Milky Way's global dynamical history, we investigate how the massive satellite galaxy M33…
