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…

It's a matter of time: Empirical Constraints on Supernova Yields and Delay Times from Dwarf Spheroidal Galaxies

Mairéad E. Heiger, Alexander P. Ji, Joshua S. Speagle +6

The chemical abundances of a stellar population encode information about nucleosynthesis and its astrophysical sites, but this information is confounded by the specific star format…

The JWST Resolved Stellar Populations Early Release Science Program. IX. The RR Lyrae Population in WLM with HST and JWST

Catherine M. Slaughter, Evan D. Skillman, Alessandro Savino +16

RR Lyrae stars are a common, dependable Population II distance indicator, and provide an independent tracer of early star formation. Here, we utilize archival HST/ACS and JWST/NIRC…

A Chemodynamical Census of the Milky Way's Ultra-Faint Compact Satellites. I. A First Population-Level Look at the Internal Kinematics and Metallicities of 19 Extremely-Low-Mass Halo Stellar Systems

William Cerny, Ting S. Li, Andrew B. Pace +13

Deep, wide-area photometric surveys have uncovered a population of compact ( 1-15 pc), extremely-low-mass ( 20-4000 ) stellar systems in th…

The Proper Motion of Draco II with HST using Multiple Reference Frames and Methodologies

Jack T. Warfield, Kevin A. McKinnon, Sangmo Tony Sohn +13

We present proper motion (PM) measurements for Draco II, an ultra-faint dwarf satellite of the Milky Way. These PMs are measured using two epochs of Hubble Space Telescope Advanced…

The Galactic Bulge exploration V.: The secular spherical and X-shaped Milky Way bulge

Z. Prudil, V. P. Debattista, L. Beraldo e Silva +9

In this work, we derive systemic velocities and subsequently orbits for 8456 RR~Lyrae stars. We identify interlopers from other Milky Way (MW) structures, which amount to 22 percen…

The HST Legacy Archival Uniform Reduction of Local Group Imaging (LAURELIN). I. Photometry and Star Formation Histories for 36 Ultra-faint Dwarf Galaxies

Meredith J. Durbin, Yumi Choi, Alessandro Savino +14

We present uniformly measured resolved stellar photometry and star formation histories (SFHs) for 36 nearby ( 400 kpc) ultra-faint dwarf galaxies (UFDs; $-7.1 \le M_V \le…

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 Galactic Bulge exploration IV.: RR~Lyrae stars as traces of the Galactic bar -- 3D and 5D analysis, extinction variation

Z. Prudil, A. Kunder, L. Beraldo e Silva +10

We created new reddening maps and derived new extinction laws from visual to near-infrared passbands using improved RR~Lyrae period-absolute magnitude-metallicity relations, thus e…
