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…
It's Not Just Star Formation: A trend of low dark matter densities in the Andromeda dwarf galaxy system
Connor S. Pickett, Michelle L. M. Collins, Justin I. Read +8
Dynamical mass modeling of Andromeda (M31) dwarf spheroidal (dSph) galaxies has revealed a growing trend of lower central dark matter (DM) densities than predicted by pure DM struc…
Clues to inside-out quenching in quiescent galaxies at : Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE
Chloe M. Cheng, Martje Slob, Mariska Kriek +16
[Abridged] Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into quenching and assembly mechanisms. Previous photometri…
Hubble Astrometry for the Local Group and Beyond in the 2030s
S. Tony Sohn, Paul Bennet, Kevin Andrew McKinnon +23
Hubble's long, stable astrometric baseline creates a rare opportunity for discovery in the Local Group and beyond. Many nearby galaxies, streams, and star clusters already have arc…
Probing the IMF in the Early Universe -- Direct measurements in the Boötes I UFD with JWST/NIRCam
Keyi Ding, Mario Gennaro, Roberto J. Avila +20
The dependence of the stellar initial mass function (IMF) on star-formation environment, particularly at low metallicities and high redshifts, remains poorly constrained. Ultra-fai…
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)…
