Gas-rich, field ultra-diffuse galaxies host few globular clusters
Michael G. Jones, Ananthan Karunakaran, Paul Bennet +7
We present Hubble Space Telescope imaging of 14 gas-rich, low surface brightness galaxies in the field at distances of 25-36 Mpc, with mean effective radii and -band central sur…
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 Quenched Satellite Population Around Milky Way Analogs
Ananthan Karunakaran, David J. Sand, Michael G. Jones +5
We study the relative fractions of quenched and star-forming satellite galaxies in the Satellites Around Galactic Analogs (SAGA) survey and Exploration of Local VolumE Satellites (…
Extending Ultra-Diffuse Galaxy Abundances to Milky Way Analogs
Ananthan Karunakaran, Dennis Zaritsky
We extend the Ultra-Diffuse Galaxy (UDG) abundance relation, , to lower halo mass hosts . We select UDG satellites from publi…
Young, blue, and isolated stellar systems in the Virgo Cluster. I. 2-D Optical spectroscopy
M. Bellazzini, L. Magrini, M. G. Jones +20
We use panoramic optical spectroscopy obtained with MUSE@VLT to investigate the nature of five candidate extremely isolated low-mass star forming regions (Blue Candidates, BCs here…
Young, blue, and isolated stellar systems in the Virgo Cluster. II. A new class of stellar system
Michael G. Jones, David J. Sand, Michele Bellazzini +21
We discuss five blue stellar systems in the direction of the Virgo cluster, analogous to the enigmatic object SECCO 1 (AGC 226067). These objects were identified based on their opt…
HI Properties of Satellite Galaxies around Local Volume Hosts
Ananthan Karunakaran, Kristine Spekkens, Rhys Carroll +5
We present neutral atomic hydrogen (HI) observations using the Robert C. Byrd Green Bank Telescope (GBT) along the lines of sight to 49 dwarf satellite galaxy candidates around eig…
Systematically Measuring Ultra-Diffuse Galaxies (SMUDGes). III. The Southern SMUDGes Catalog
Dennis Zaritsky, Richard Donnerstein, Ananthan Karunakaran +5
We present a catalog of 5598 ultra-diffuse galaxy (UDG) candidates with effective radius arcsec distributed throughout the southern portion of the DESI Legacy Imaging S…
Tucana B: A Potentially Isolated and Quenched Ultra-faint Dwarf Galaxy at D1.4 Mpc
D. J. Sand, B. Mutlu-Pakdil, M. G. Jones +7
We report the discovery of Tucana B, an isolated ultra-faint dwarf galaxy at a distance of D=1.4 Mpc. Tucana B was found during a search for ultra-faint satellite companions to the…
