The Halo Gas of Local Spiral Galaxies and the Link to Gaseous Satellites
Yong Zheng, Jingyao Zhu, Ben Wertz +2
Gaseous satellites orbiting massive host galaxies experience gas stripping and may contribute additional gas to the hosts' circumgalactic medium (CGM). We identify a sample of 21 l…
Identifying signatures of inflow onto face-on galaxies using the Balmer decrement
Meghna Sitaram, Hui Li, Yong Zheng +4
Isolated star-forming galaxies require inflows of fresh gas from the surrounding medium to sustain episodes of star formation over time. However, there are very few direct detectio…
Mainly on the Plane: Observing the Extended, Ionized Disks of Milky Way Analogs in IllustrisTNG
Michael Messere, Kirill Tchernyshyov, Mary E. Putman +4
This paper explores the extent to which the circumgalactic medium (CGM) of Milky Way-like galaxies is located in an extended, ionized, disklike structure. To test this hypothesis,…
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…
The Plane Quasar Survey: An Ionized Extension of the Magellanic Stream on the Northern Side of the Galactic Plane
Bo-Eun Choi, Jessica K. Werk, Kirill Tchernyshyov +5
The Magellanic Stream (MS) is a vast gaseous structure in the Milky Way halo, containing most of its mass in ionized form and tracing the interaction between the Large and Small Ma…
A Catalog of Galactic Atomic Hydrogen Position-Position-Velocity Filaments
M. E. Putman, D. A. Kim, S. E. Clark +3
We present a catalog of 3D Galactic HI filaments over 1/3 of the sky using Galactic Arecibo L-band Feed Array HI (GALFA-HI) data. The 3D filaments are defined to be linear HI featu…
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 Karl G. Jansky Very Large Array Local Group L-band Survey (LGLBS)
Eric W. Koch, Adam K. Leroy, Erik W. Rosolowsky +45
We present the Local Group L-Band Survey (LGLBS), a Karl G. Jansky Very Large Array (VLA) survey producing the highest quality 21-cm and 1-2 GHz radio continuum images to date for…
Simulating High-Velocity Clouds in the Observational Plane: An Initial Study with the Smith Cloud
Lori E. Porter, Matthew Abruzzo, Greg L. Bryan +3
High-velocity clouds (HVCs) may fuel future star formation in the Milky Way, but they must first survive their passage through the hot halo. While recent work has improved our unde…
Introducing the Descriptive Parametric Model: Gaseous Profiles for Galaxies, Groups, and Clusters
Benjamin D. Oppenheimer, G. Mark Voit, Yannick M. Bahé +14
We develop and present the Descriptive Parametric Model (DPM), a tool for generating profiles of gaseous halos (pressure, electron density, and metallicity) as functions of radius,…
A Search for 3-mm Molecular Absorption Line Transitions in the Magellanic Stream
Lucille Steffes, Daniel R. Rybarczyk, Snežana Stanimirović +14
The Magellanic Stream, a tidal tail of diffuse gas falling onto the Milky Way, formed by interactions between the Small and Large Magellanic Clouds, is primarily composed of neutra…
The Metallicity Mapping of the Ionized Diffuse Gas at the Milky Way Disk-halo Interface
Bo-Eun Choi, Jessica K. Werk, Kirill Tchernyshyov +5
Metals in the diffuse, ionized gas at the boundary between the Milky Way's interstellar medium (ISM) and circumgalactic medium (CGM), known as the disk-halo interface (DHI), are va…
