The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1
Adam Smercina, Eric F. Bell, Benjamin F. Williams +15
We present deep HST imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an eni…
The Panchromatic Hubble Andromeda Southern Treasury (PHAST). II. The Spatially Resolved Recent Star Formation History in M31
Tobin M. Wainer, Benjamin F. Williams, Zhuo Chen +19
We use Hubble Space Telescope optical imaging from the Panchromatic Hubble Andromeda Southern Treasury (PHAST) to measure the spatially resolved recent star formation history (SFH)…
Stars Born in the Wind II: Widespread Extra-planar Star Formation in M82's Halo
Vaishnav V. Rao, Eric F. Bell, Adam Smercina +6
Galaxies evolve in tandem with their environments -- mergers and gas inflows drive galaxy growth while galactic outflows launched by supernovae may seed the galactic environment wi…
The Timescales of Embedded Star Formation as Observed in STARFORGE
Tobin M. Wainer, Julianne J. Dalcanton, Michael Y. GrudiÄ +7
Star formation occurs within dusty molecular clouds that are then disrupted by stellar feedback. However, the timing and physical mechanisms that govern the transition from deeply…
Stars Born in the Wind: M82's Outflow and Halo Star Formation
Vaishnav V. Rao, Adam Smercina, Eric F. Bell +8
Starburst galaxies, like M82, launch kiloparsec-scale galactic outflows that interact with the circumgalactic medium (CGM) in complex ways. Apart from enriching the CGM with metals…
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…
