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…
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…
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…
