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…
A census of dwarf galaxy satellites around LMC-mass galaxy NGC 2403
Jeffrey L. Carlin, David J. Sand, Burcin Mutlu-Pakdil +11
We present the first comprehensive census of the satellite population around a Large Magellanic Cloud (LMC) stellar-mass galaxy, as part of the Magellanic Analog Dwarf Companions a…
Low-density star cluster formation: discovery of a young faint fuzzy on the outskirts of the low-mass spiral galaxy NGC 247
Aaron J. Romanowsky, Søren S. Larsen, Alexa Villaume +21
The classical globular clusters found in all galaxy types have half-light radii of 2-4 pc, which have been tied to formation in the dense cores of giant molecular…
The Dual Role of Outflows in Quenching Satellites of Low-Mass Hosts: NGC 3109
Christopher T. Garling, Annika H. G. Peter, Kristine Spekkens +4
While dwarf galaxies observed in the field are overwhelmingly star-forming, dwarf galaxies in environments as dense or denser than the Milky Way are overwhelmingly quenched. In thi…
Hubble Space Telescope Imaging of Isolated Local Volume Dwarfs GALFA-Dw3 and Dw4
P. Bennet, D. J. Sand, D. Crnojević +16
We present observations of the dwarf galaxies GALFA Dw3 and GALFA Dw4 with the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope (HST). These galaxies were initially…
Hubble Space Telescope Observations of Two Faint Dwarf Satellites of Nearby LMC Analogs from MADCASH
Jeffrey L. Carlin, Burcin Mutlu-Pakdil, Denija Crnojevic +11
We present a deep Hubble Space Telescope (HST) imaging study of two dwarf galaxies in the halos of Local Volume Large Magellanic Cloud (LMC) analogs. These dwarfs were discovered a…
Hubble Space Telescope Imaging of Antlia B: Star Formation History and a New Tip of the Red Giant Branch Distance
Jonathan R. Hargis, S. Albers, D. Crnojević +8
A census of the satellite population around dwarf galaxy primary hosts in environments outside the Local Group is essential to understanding CDM galaxy formation and evolution o…
Tidal destruction in a low mass galaxy environment: the discovery of tidal tails around DDO 44
Jeffrey L. Carlin, Christopher T. Garling, Annika H. G. Peter +10
We report the discovery of a ( kpc) long stellar tidal stream emanating from the dwarf galaxy DDO 44, a likely satellite of Local Volume galaxy NGC 2403 located…
Hyper Wide Field Imaging of the Local Group Dwarf Irregular Galaxy IC 1613: An Extended Component of Metal-poor Stars
Ragadeepika Pucha, Jeffrey L. Carlin, Beth Willman +10
Stellar halos offer fossil evidence for hierarchical structure formation. Since halo assembly is predicted to be scale-free, stellar halos around low-mass galaxies constrain proper…
Mapping the Tidal Disruption of the Hercules Dwarf: A Wide-Field DECam Imaging Search for RR Lyrae Stars
Christopher Garling, Beth Willman, David J. Sand +10
We investigate the hypothesized tidal disruption of the Hercules ultra-faint dwarf galaxy (UFD). Previous tidal disruption studies of the Hercules UFD have been hindered by the hig…
Deep Subaru Hyper Suprime-Cam observations of Milky Way satellites Columba I and Triangulum II
Jeffrey L. Carlin, David J. Sand, Ricardo R. Munoz +9
We present deep, wide-field Subaru Hyper Suprime-Cam photometry of two recently discovered satellites of the Milky Way (MW): Columba I and Triangulum II. The color magnitude diagra…
First results from the MADCASH Survey: A Faint Dwarf Galaxy Companion to the Low Mass Spiral Galaxy NGC 2403 at 3.2 Mpc
Jeffrey L. Carlin, David J. Sand, Paul Price +13
We report the discovery of the faintest known dwarf galaxy satellite of an LMC stellar-mass host beyond the Local Group, based on deep imaging with Subaru/Hyper Suprime-Cam. MADCAS…
Evidence That Hydra I is a Tidally Disrupting Milky Way Dwarf Galaxy
Jonathan R. Hargis, B. Kimmig, B. Willman +6
The Eastern Banded Structure (EBS) and Hydra~I halo overdensity are very nearby (d 10 kpc) objects discovered in SDSS data. Previous studies of the region have shown that EB…
Antlia B: A faint dwarf galaxy member of the NGC 3109 association
D. J. Sand, K. Spekkens, D. Crnojević +4
We report the discovery of Antlia B, a faint dwarf galaxy at a projected distance of 72 kpc from NGC 3109 (15 mag), the primary galaxy of the NGC 3109 dwarf a…
A Comprehensive Archival Search for Counterparts to Ultra-Compact High Velocity Clouds: Five Local Volume Dwarf Galaxies
D. J. Sand, D. Crnojević, P. Bennet +17
We report five Local Volume dwarf galaxies (two of which are presented here for the first time) uncovered during a comprehensive archival search for optical counterparts to ultra-c…
Globular Cluster Systems and their Host Galaxies: Comparison of Spatial Distributions and Colors
Jonathan R. Hargis, Katherine L. Rhode
We present a study of the spatial and color distributions of four early-type galaxies and their globular cluster (GC) systems observed as part of our ongoing wide-field imaging sur…
Too Many, Too Few, or Just Right? The Predicted Number and Distribution of Milky Way Dwarf Galaxies
Jonathan R. Hargis, Beth Willman, Annika H. G. Peter
We predict the spatial distribution and number of Milky Way dwarf galaxies to be discovered in the DES and LSST surveys, by completeness correcting the observed SDSS dwarf populati…
