Stellar proper motions in the outskirts of classical dwarf spheroidal galaxies with Gaia EDR3
Yuewen Qi, Paul Zivick, Andrew B. Pace +2
We use Gaia EDR3 data to identify stars associated with six classical dwarf spheroidals (Draco, Ursa Minor, Sextans, Sculptor, Fornax, Carina) at their outermost radii, beyond thei…
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…
Dark and luminous mass components of Omega Centauri with stellar kinematics
Addy J. Evans, Louis E. Strigari, Paul Zivick
We combine proper motion data from EDR3 and HST with line-of-sight velocity data to study the stellar kinematics of the Omega Centauri globular cluster. Using a steady-state…
