Exploring the Structures and Substructures of the Andromeda Satellite Dwarf Galaxies Cassiopeia III, Perseus I, and Lacerta I
Katherine L. Rhode, Nicholas J. Smith, Denija Crnojevic +8
We present results from wide-field imaging of the resolved stellar populations of the dwarf spheroidal galaxies Cassiopeia III (And XXXII) and Perseus I (And XXXIII), two satellite…
A Search for Gas-Rich Dwarf Galaxies in the Local Universe with ALFALFA and the WIYN One Degree Imager
Katherine L. Rhode, Nicholas J. Smith, William F. Janesh +5
We present results from an optical search for Local Group dwarf galaxy candidates associated with the Ultra-Compact High Velocity Clouds (UCHVCs) discovered by the ALFALFA neutral…
Catching Tidal Dwarf Galaxies at a Later Evolutionary Stage with ALFALFA
Laurin M. Gray, Katherine L. Rhode, Lukas Leisman +11
We present deep optical imaging and photometry of four objects classified as "Almost-Dark" galaxies in the ALFALFA survey because of their gas-rich nature and extremely faint or mi…
The ALFALFA Almost-Dark Galaxy AGC~229101: A Two Billion Solar Mass HI Cloud with a Very Low Surface Brightness Optical Counterpart
Lukas Leisman, Katherine L. Rhode, Catherine Ball +11
We present results from deep HI and optical imaging of AGC 229101, an unusual HI source detected at v = 7116 km/s in the ALFALFA survey. Initially classified as a can…
VLA Imaging of HI-bearing Ultra-Diffuse Galaxies from the ALFALFA Survey
Lexi Gault, Lukas Leisman, Elizabeth A. K. Adams +12
Ultra-diffuse galaxies have generated significant interest due to their large optical extents and low optical surface brightnesses, which challenge galaxy formation models. Here we…
Robust HI kinematics of gas-rich ultra-diffuse galaxies: hints of a weak-feedback formation scenario
Pavel E. Mancera Piña, Filippo Fraternali, Kyle A. Oman +15
We study the gas kinematics of a sample of six isolated gas-rich low surface brightness galaxies, of the class called ultra-diffuse galaxies (UDGs). These galaxies have recently be…
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…
The Impact of Assembly Bias on the Galaxy Content of Dark Matter Halos
Idit Zehavi, Sergio Contreras, Nelson Padilla +3
We study the dependence of the galaxy content of dark matter halos on large-scale environment and halo formation time using semi-analytic galaxy models applied to the Millennium si…
