Kinematics and metallicity of the dwarf spheroidal galaxy Andromeda XVIII
Kateryna Kvasova, Evan N. Kirby, Rachael L. Beaton
Andromeda XVIII is an isolated dwarf galaxy 579 kpc away from the nearest large galaxy, M31. It is a candidate "backsplash galaxy" that might have been affected by a close passage…
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…
The Proper Motion of Pyxis: the first use of Adaptive Optics in tandem with HST on a faint halo object
Tobias K. Fritz, Sean T. Linden, Paul Zivick +13
We present a proper motion measurement for the halo globular cluster Pyxis, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data as the second, separated by a…
Extinction Maps towards the Milky Way Bulge: 2D and 3D Tests with APOGEE
M. Schultheis, G. Zasowski, C. Allende Prieto +15
Galactic interstellar extinction maps are powerful and necessary tools for Milky Way structure and stellar population analyses, particularly toward the heavily-reddened bulge and i…
Stellar Kinematics of the Andromeda II Dwarf Spheroidal Galaxy
Nhung Ho, Marla C. Geha, Ricardo R. Munoz +7
We present kinematical profiles and metallicity for the M31 dwarf spheroidal (dSph) satellite galaxy Andromeda II (And II) based on Keck DEIMOS spectroscopy of 531 red giant branch…
Very Early Ultraviolet and Optical Observations of the Type Ia Supernova 2009ig
Ryan J. Foley, P. J. Challis, A. V. Filippenko +18
Supernova (SN) 2009ig was discovered 17 hours after explosion by the Lick Observatory Supernova Search, promptly classified as a normal Type Ia SN (SN Ia), peaked at V = 13.5 mag,…
