The JWST Resolved Stellar Populations Early Release Science Program IV: The Star Formation History of the Local Group Galaxy WLM
Kristen. B. W. McQuinn, Max J. B. Newman, Alessandro Savino +23
We present the first star formation history (SFH) and age-metallicity relation (AMR) derived from resolved stellar populations imaged with the JWST NIRCam instrument. The target is…
A Comparison Between the Morphologies and Structures of Dwarf Galaxies with and without Active Massive Black Holes
Seth J. Kimbrell, Amy E. Reines, Jenny E. Greene +1
We study the morphologies and structures of 57 dwarf galaxies that are representative of the general population of dwarf galaxies, and compare their demographics to a sample of dwa…
X-ray Properties of Optically Variable Low-mass AGN Candidates
Alexander Messick, Vivienne Baldassare, Marla Geha +1
We present an X-ray analysis of fourteen nearby (z < 0.044) AGN in low mass galaxies (M_* <= 5*10^9 Msun) selected based on their optical variability (Baldassare et al. 2020). Comp…
DELVE 6: An Ancient, Ultra-Faint Star Cluster on the Outskirts of the Magellanic Clouds
W. Cerny, A. Drlica-Wagner, T. S. Li +23
We present the discovery of DELVE 6, an ultra-faint stellar system identified in the second data release of the DECam Local Volume Exploration (DELVE) survey. Based on a maximum-li…
The Hubble Space Telescope Survey of M31 Satellite Galaxies II. The Star Formation Histories of Ultra-Faint Dwarf Galaxies
A. Savino, D. R. Weisz, E. D. Skillman +34
We present the lifetime star formation histories (SFHs) for six ultra-faint dwarf (UFD; , ) satellite galaxies of M31 based on…
The JWST Resolved Stellar Populations Early Release Science Program II. Survey Overview
Daniel R. Weisz, Kristen B. W. McQuinn, Alessandro Savino +39
We present the JWST Resolved Stellar Populations Early Release Science (ERS) science program. We obtained 27.5 hours of NIRCam and NIRISS imaging of three targets in the Local Grou…
