The Hubble Space Telescope Survey of M31 Satellite Galaxies IV. Survey Overview and Lifetime Star Formation Histories
A. Savino, D. R. Weisz, A. E. Dolphin +35
From orbits of HST imaging, we present deep homogeneous resolved star color-magnitude diagrams that reach the oldest main sequence turnoff and uniformly measured star forma…
The JWST Resolved Stellar Populations Early Release Science Program V. DOLPHOT Stellar Photometry for NIRCam and NIRISS
Daniel R. Weisz, Andrew E. Dolphin, Alessandro Savino +38
We present NIRCam and NIRISS modules for DOLPHOT, a widely-used crowded field stellar photometry package. We describe details of the modules including pixel masking, astrometric al…
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…
New constraints on the structure of the nuclear stellar cluster of the Milky Way from star counts and MIR imaging
E. Gallego-Cano, R. Schödel, F. Nogueras-Lara +5
The Milky Way nuclear star cluster (MWNSC) is a crucial laboratory for studying the galactic nuclei of other galaxies, but its properties have not been determined unambiguously unt…
The Orbit and Origin of the Ultra-faint Dwarf Galaxy Segue 1
T. K. Fritz, M. Lokken, N. Kallivayalil +4
We present the first proper motion measurement for an ultra-faint dwarf spheroidal galaxy, Segue 1, using SDSS and LBC data as the first and second epochs separated by a baseline o…
The Proper Motion of Pyxis: the first use of Adaptive Optics in tandem with HST on a faint halo object
Tobias K. Fritz, Sean T. Linden, Paul Zivick +13
We present a proper motion measurement for the halo globular cluster Pyxis, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data as the second, separated by a…
