oMEGACat I: MUSE spectroscopy of 300,000 stars within the half-light radius of Centauri
M. S. Nitschai, N. Neumayer, C. Clontz +17
Omega Centauri ( Cen) is the most massive globular cluster of the Milky Way and has been the focus of many studies that reveal the complexity of its stellar populations and kine…
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 GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) II: Characterization of 47 Tuc with Bayesian Statistics
Mirko Simunovic, Thomas H. Puzia, Bryan Miller +5
We present a photometric analysis of globular cluster 47 Tuc (NGC\,104), using near-IR imaging data from the GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) which is in operatio…
Multiple Stellar Populations in Metal-Poor Globular Clusters with JWST: a NIRCam view of M92
Tuila Ziliotto, Antonino P. Milone, Anna F. Marino +10
Recent work on metal-intermediate globular clusters (GCs) with [Fe/H]= and has illustrated the theoretical behavior of multiple populations in photometric diagrams ob…
On the role of dust and mass loss in the extended main sequence turnoff of star clusters: the case of NGC 1783
F. D'Antona, F. Dell'Agli, M. Tailo +6
The Color Magnitude Diagram (CMD) morphology of the "extended" main sequence turnoff (eMSTO) and upper main sequence (MS) of the intermediate age ( Gyr) Large Magellani…
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…
