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…
ELVES-Dwarf. II. A Systematic Search for Satellite Systems of Dwarf Galaxies in the Local Volume
Jiaxuan Li, Jenny E. Greene, Shany Danieli +7
We present the Exploration of Local VolumE Satellites of Dwarf Galaxies (ELVES-Dwarf) survey, a systematic census of satellite systems around dwarf hosts in the Local Volume. Our f…
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…
Willman 1 Revisited: The Kinematics, Chemistry, and Orbital Properties of a Potentially-Disrupting Dwarf Galaxy
Camille Chiu, Marla Geha, William Cerny +4
The ultra-faint Milky Way satellite Willman 1 (W1; ; pc) was the first stellar over-density found via resolved stars in the Sloan Digital Sky Surv…
The Keck/DEIMOS Stellar Archive: I. Uniform Velocities and Metallicities for 78 Milky Way Dwarf Galaxies and Globular Clusters
Marla Geha, Debora Pelliccia, J. Xavier Prochaska +5
We present a homogeneous spectroscopic dataset of 22,339 stars in 78 Milky Way dwarf galaxy satellites and globular clusters. All data were taken with the Keck II telescope and Dee…
