The Triangulum Extended (TREX) Survey: The Stellar Disk Dynamics of M33 as a Function of Stellar Age
A. C. N. Quirk, P. Guhathakurta, K. Gilbert +8
Triangulum, M33, is a low mass, relatively undisturbed spiral galaxy that offers a new regime in which to test models of dynamical heating. In spite of its proximity, the dynamical…
Star Formation Histories of Ultra-Faint Dwarf Galaxies: environmental differences between Magellanic and non-Magellanic satellites?
Elena Sacchi, Hannah Richstein, Nitya Kallivayalil +18
We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2, Sagittarius 2, Trian…
HST Proper Motions of NGC 147 and NGC 185: Orbital Histories and Test of Dynamically Coherent Andromeda Satellite Plane
Sangmo Tony Sohn, Ekta Patel, Mark A. Fardal +4
We present the first proper motion (PM) measurements for the dwarf elliptical galaxies NGC 147 and NGC 185, two satellite galaxies of M31, using multi-epoch HST imaging data with t…
The Orbital Histories of Magellanic Satellites Using Gaia DR2 Proper Motions
Ekta Patel, Nitya Kallivayalil, Nicolas Garavito-Camargo +6
With the release of Gaia DR2, it is now possible to measure the proper motions (PMs) of the lowest mass, ultra-faint satellite galaxies in the Milky Way's (MW) halo for the first t…
Asymmetric Drift of Andromeda Analogs in the IllustrisTNG Simulation
Amanda C. N. Quirk, Ekta Patel
We analyze the kinematics as a function of stellar age for Andromeda (M31) mass analogs from the IllustrisTNG cosmological simulation. We divide the star particles into four age gr…
Astro2020 Science White Paper: Construction of an L* Galaxy: the Transformative Power of Wide Fields for Revealing the Past, Present and Future of the Great Andromeda System
Karoline M. Gilbert, Erik J. Tollerud, Jay Anderson +34
The Great Andromeda Galaxy (M31) is the nexus of the near-far galaxy evolution connection and a principal data point for near-field cosmology. Due to its proximity (780 kpc), M31 c…
