Baryon dominated ultra-diffuse galaxies
Pavel E. Mancera Piña, Filippo Fraternali, Elizabeth A. K. Adams +1
By means of interferometic 21-cm observations and a 3D kinematic modeling technique, we study the gas kinematics of six HI-rich ultra-diffuse galaxies (UDGs). We derive robust circ…
Off the baryonic Tully-Fisher relation: a population of baryon-dominated ultra-diffuse galaxies
Pavel E. Mancera Piña, Filippo Fraternali, Elizabeth A. K. Adams +17
We study the gas kinematics traced by the 21-cm emission of a sample of six HIrich low surface brightness galaxies classified as ultra-diffuse galaxies (UDGs). Using the 3D kine…
Five Gas-rich Ultra-faint Dwarf Galaxy Candidates Discovered in WIYN Imaging of ALFALFA Sources
William Janesh, Katherine L. Rhode, John J. Salzer +5
We present results from the analysis of WIYN pODI imaging of 23 ultra-compact high-velocity clouds (UCHVCs), which were identified in the ALFALFA HI survey as possible dwarf galaxi…
The Enigmatic (Almost) Dark Galaxy Coma P: Distance Measurement and Stellar Populations from HST Imaging
Samantha W. Brunker, Kristen B. W. McQuinn, John J. Salzer +9
We present Hubble Space Telescope (HST) observations of the low surface brightness (SB) galaxy Coma P. This system was first discovered in the Arecibo Legacy Fast ALFA HI survey an…
