The GASKAP-HI Survey towards the Magellanic Clouds: Cold Atomic Gas Survival and Evolution in the Large Magellanic Cloud
Hongxing Chen, Snezana Stanimirovic, James Dempsey +18
We use atomic hydrogen (HI) absorption detections from the GASKAP-HI survey to investigate the properties of cold atomic gas in the Large Magellanic Cloud (LMC). Using the radiativ…
Anomalously high deuterium fractionation in a galactic translucent cloud: a challenge to chemical models
Gan Luo, Zhi-Yu Zhang, Thomas G. Bisbas +8
Deuterated (D-) species have long been proposed to diagnose the physical conditions and chemical evolution of cold dense molecular clouds. While deuterium fractionation has been ex…
The Multi-phase HI of the Milky Way and Nearby Galaxies
Marc-Antoine Miville-Deschênes, J. R. Dawson, Narendra Nath Patra +30
Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimate…
CO-dark molecular gas traced by HCO in the diffuse interstellar medium
Daniel R. Rybarczyk, Michael P. Busch, J. R. Dawson +2
A classic problem in the study of the interstellar medium (ISM) is the near-invisibility of molecular hydrogen (H) in cold environments. Observations of CO emission are typical…
Revisiting ram pressure stripping in Wolf-Lundmark-Melotte: No evidence for stripped HI with LGLBS
Daniel R. Rybarczyk, Eric W. Koch, Fabian Caballero Vargas +12
We analyze HI 21-cm observations of the Local Group dwarf galaxy Wolf-Lundmark-Melotte (WLM) from the Local Group L-Band Survey to search for evidence of ram pressure stripping. Wh…
The Local Group L-band Survey: Probing Cold Atomic Gas in IC10 with Neutral Hydrogen Absorption
Ioana A. Stelea, Snezana Stanimirovic, Nickolas M. Pingel +20
We present the first localized detections of the cold neutral medium (CNM) in IC10, offering a rare view of dense atomic gas in a low-metallicity (0.27 solar metallicity) dwarf gal…
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…
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…
Revisiting the Vertical Distribution of HI Absorbing Clouds in the Solar Neighborhood. II. Constraints from a Large Catalog of 21 cm Absorption Observations at High Galactic Latitudes
Daniel R. Rybarczyk, Trey V. Wenger, Snezana Stanimirović
The cold neutral medium (CNM) is where neutral atomic hydrogen (HI) is converted into molecular clouds, so the structure and kinematics of the CNM are key drivers of galaxy evoluti…
Revisiting the Vertical Distribution of HI Absorbing Clouds in the Solar Neighborhood
Trey V. Wenger, Daniel R. Rybarczyk, Snežana Stanimirović
The vertical distribution of cold neutral hydrogen (HI) clouds is a constraint on models of the structure, dynamics, and hydrostatic balance of the interstellar medium. In 1978, Cr…
Probing the Conditions for the Hı-to-H Transition in the Interstellar Medium
Gyueun Park, Min-Young Lee, Shmuel Bialy +9
In this paper, we investigate the conditions for the HI-to-H transition in the solar neighborhood by analyzing HI emission and absorption measurements toward 58 Galactic line…
Atomic Hydrogen in the Milky Way: A Stepping Stone in the Evolution of Galaxies
Naomi M. McClure-Griffiths, Snezana Stanimirovic, Daniel R. Rybarczyk
Atomic hydrogen (HI) is a critical stepping stone in the gas evolution cycle of the interstellar medium (ISM) of the Milky Way. Hi traces both the cold, premolecular state before s…
Shaken or stirred: the diffuse interstellar medium with exceptionally high SiO abundance
Daniel R. Rybarczyk, Snezana Stanimirovic, Antoine Gusdorf
Interstellar shocks, a key element of stellar feedback processes, shape the structure of the interstellar medium (ISM) and are essential for the chemistry, thermodynamics, and kine…
The role of neutral hydrogen in setting the abundances of molecular species in the Milky Way's diffuse interstellar medium. II. Comparison between observations and theoretical models
Daniel R. Rybarczyk, Munan Gong, Snezana Stanimirovic +6
We compare observations of HI from the Very Large Array (VLA) and the Arecibo Observatory and observations of HCO from the Atacama Large Millimeter/submillimeter Array (ALMA) a…
The role of neutral hydrogen in setting the abundances of molecular species in the Milky Way's diffuse interstellar medium. I. Observational constraints from ALMA and NOEMA
Daniel R. Rybarczyk, Snezana Stanimirovic, Munan Gong +7
We have complemented existing observations of HI absorption with new observations of HCO, CH, HCN, and HNC absorption from the Atacama Large Millimeter/submillimeter Array…
Small-scale structure traced by neutral hydrogen absorption in the direction of multiple-component radio continuum sources
Daniel R. Rybarczyk, Snezana Stanimirovic, Ellen G. Zweibel +4
We have studied the small scale distribution of atomic hydrogen (HI) using 21-cm absorption spectra against multiple-component background radio continuum sources from the 21-SPONGE…
