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…
Pavo: Stellar feedback in action in a low-mass dwarf galaxy
Michael G. Jones, Martin P. Rey, David J. Sand +13
MeerKAT observations of the recently discovered, extremely low mass galaxy, Pavo, have revealed a neutral gas (HI) reservoir that was undetected in archival HI single dish data. We…
The NGC3109 Satellite System: The First Systematic Resolved Search for Dwarf Galaxies Around a SMC-mass Host
Amandine Doliva-Dolinsky, Burçin Mutlu-Pakdil, Denija CrnojeviÄ +38
We report the results of the deepest search to date for dwarf galaxies around NGC3109, a barred spiral galaxy with a mass similar to that of the Small Magellanic Cloud (SMC), using…
Are Gas-rich Ultra-diffuse Galaxies and Field Dwarfs Distinct?
Khadeejah Motiwala, Ananthan Karunakaran, Kristine Spekkens +5
We explore the differences in gas-rich field Ultra-Diffuse Galaxies (UDGs) and classical dwarf galaxies using an extensive atomic gas (HI) follow-up survey of optically-selected UD…
