Detecting HI Self-Absorption using Neural Networks
Eric G. M. Muller, Naomi M. McClure-Griffiths, Hiep Nguyen +5
Cold atomic hydrogen plays a crucial role in the life cycle of interstellar gas. It serves as the intermediary phase in the condensation and cooling processes that bridge the warm…
A Detailed GASKAP-HI View of Shells and Loops in the Magellanic Bridge
Shin-Jeong Kim, Antoine Marchal, N. M. McClure-Griffiths +19
We present 8 pc-scale GASKAP-HI observations of an HI shell (diameter \sim130 pc) associated with the Hαshell DEM171 in the Magellanic Bridge. The Bridge's diffuse, HI-dominated en…
IViS: Interferometric Visibility-domain inversion Software - A GPU-accelerated Python framework for joint deconvolution with ASKAP
A. Marchal, N. M. McClure-Griffiths, J. Dempsey +9
Wide-field spectral-line imaging with modern radio interferometers remains challenging when the emission is extended, multiscale, and distributed over many overlapping pointings. A…
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…
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…
Revealing the cold skeleton of the Magellanic Clouds and the Magellanic Bridge with ASKAP
James Dempsey, N. M. McClure-Griffiths, Antoine Marchal +14
We present the GASKAP-HI pilot absorption survey of neutral hydrogen (HI) in the Magellanic system. This survey provides 3219 sightlines across the Large (LMC) and Small Magellanic…
A High-resolution Study of the Cold Neutral Medium in and around 30 Doradus
Gyueun Park, Min-Young Lee, John M. Dickey +17
With the aim of evaluating the roles of the cold neutral medium (CNM) in the cloud-scale baryon cycle, we perform a high-resolution study of the CNM in and around the extreme star-…
Study of HI Turbulence in the SMC Using Multi-point Structure Functions
Bumhyun Lee, Min-Young Lee, Jungyeon Cho +19
Turbulence in the interstellar medium (ISM) plays an important role in many physical processes, including forming stars and shaping complex ISM structures. In this work, we investi…
Multi-wavelength probes of the Milky Way's Cold Interstellar Medium: Radio HI and Optical KI Absorption with GASKAP and GALAH
Hiep Nguyen, Sven Buder, Juan D. Soler +19
We present a comparative analysis of interstellar hydrogen (HI) and potassium (KI) absorption from the radio and optical surveys, GASKAP and GALAH, to study the physical and kinema…
Considerations with stacking absorption spectra: cold HI gas in cirrus region of the Milky Way
