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…

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 Crnojević +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…
