Rubin Observatory Reveals a Dust-Shrouded Halo Globular Cluster in Ophiuchus

Aashay Pai, William Cerny, Andrew B. Pace +9

We present the discovery of the Milky Way satellite Rubin-GC1 (Rubin J1628-1735) using data from the NSF-DOE Vera C. Rubin Observatory's Early Data Preview 2. The system was discov…

Discovery of the Distant, Ultra-Faint Milky Way Satellite Aquarius IV with the Vera C. Rubin Observatory Early Data Preview 2

William Cerny, Aashay Pai, Alex Drlica-Wagner +16

We present the discovery of Aquarius IV (Rubin J22010234) -- the first ultra-faint Milky Way satellite to be identified using data from the Vera C. Rubin Observatory. This syste…

The Metallicity Distribution of the Ultra-Faint Dwarf Galaxy Segue 1

Daisy Bissonette, Alexander P. Ji, Joshua D. Simon +6

Ultra-faint dwarf galaxies (UFDs; stellar masses ) offer unique insights into early chemical evolution in low-mass systems. However, interpreting their metalli…

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…

A Path to an All-Sky Survey with Roman

Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93

A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…

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 Keck/DEIMOS Stellar Archive: II. Dynamical Masses and Metallicities for a Uniform Sample of Milky Way Satellites

Marla Geha

Population-level studies of Milky Way satellites used to constrain dark matter or the threshold of galaxy formation often rely on velocity dispersions and metallicities derived fro…
