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 DECam MAGIC Survey: Investigating the Jet Stellar Stream with Photometric Metallicities
H. Q. Do, A. Chiti, P. S. Ferguson +27
Stellar streams are dynamically fragile structures formed by the tidal disruption of dwarf galaxies and stellar clusters. These objects are valuable tracers of the gravitational po…
DELVE Milky Way Satellite Galaxy Census I: Satellite Population and Survey Selection Function in DES, DELVE, and Pan-STARRS
C. Y. Tan, A. Drlica-Wagner, A. B. Pace +84
The properties of Milky Way satellite galaxies have important implications for galaxy formation, reionization, and the fundamental physics of dark matter. However, the population o…
Identifying Dwarfs of MC Analog GalaxiEs (ID-MAGE): The Search for Satellites Around Low-Mass Hosts
Laura Congreve Hunter, Burçin Mutlu-Pakdil, David J. Sand +11
We present results from ID-MAGE (Identifying Dwarfs of MC Analog GalaxiEs), a survey aimed at identifying and characterizing unresolved satellite galaxies around 36~nearby LMC- and…
Star formation histories and gas content limits of three ultra-faint dwarfs on the periphery of M31
Michael G. Jones, David J. Sand, Paul Bennet +9
We present Hubble Space Telescope (HST) imaging of Pegasus V and Pisces VII, along with a re-analysis of the archival imaging of Pegasus W, and Jansky Very Large Array (VLA) neutra…
SEAMLESS Survey: Four Faint Dwarf Galaxies Tracing Low-Mass Galaxy Evolution Across Environments
Catherine E. Fielder, Michael G. Jones, David J. Sand +11
We report on four Local Volume dwarf galaxies identified through our ongoing SEmi-Automated Machine LEarning Search for Semi-resolved galaxies (SEAMLESS): Hydrus A, LEDA 486718, Ce…
