TiNy Titans HI: Discovering Satellites via HI Gas in an Isolated, Compact Group of Dwarf Galaxies

Sabrina Stierwalt, Nicholas Luber, Zelie Goldberg Little +7

We report on the HI content of an isolated, compact group of 6 dwarf galaxies at a distance of 145 Mpc. The distribution and kinematics of the HI, including multiple gaseous bridge…

A Galactic Transformation -- Understanding the SMC's Structural and Kinematic Disequilibrium

Himansh Rathore, Gurtina Besla, Roeland P. van der Marel +1

The SMC is in disequilibrium. Gas line-of-sight (LoS) velocity maps show a gradient of km s, generally interpreted as a rotating gas disk consistent with the Tully-…

Shaping the Milky Way. II. The dark matter halo's response to the LMC's passage in a cosmological context

Elise Darragh-Ford, Nicolas Garavito-Camargo, Arpit Arora +15

The distribution of dark matter in the Milky Way (MW) is expected to exhibit a large-scale dynamical response to the recent infall of the LMC. This event produces a dynamical frict…

Caught in the Cosmic Web: Evidence for Ram-Pressure Stripping of a Low-Mass Galaxy by the Cosmic Web

Nicholas Luber, Sabrina Stierwalt, George C. Privon +6

We present interferometric radio observations of the neutral atomic gas in AGC 727130, a low-mass, gas-rich, field galaxy lacking significant star-formation. The atomic gas in AGC…

The Orbits of Isolated Dwarfs in the Local Group from New 3D Kinematics: Constraints on First Infall, Backsplash, and Quenching Mechanisms

Paul Bennet, Ekta Patel, Sangmo Tony Sohn +8

It is commonly supposed that quenched field dwarfs near the edge of the Local Group (LG) are backsplash galaxies, having previously orbited within the Milky Way (MW) or M31's viria…

Response of the LMC's Bar to a Recent SMC Collision and Implications for the SMC's Dark Matter Profile

Himansh Rathore, Gurtina Besla, Kathryne J. Daniel +1

The LMC's stellar bar is offset from the outer disk center, tilted from the disk plane, and does not drive gas inflows. These properties are atypical of bars in gas-rich galaxies,…
