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…
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-…
Tracing Gas Kinematics and Interactions between H II Regions and Molecular Clouds using VLA Observations of Recombination Lines and Hydroxyl
E. Cappellazzo, J. R. Dawson, Mark Wardle +7
Observational studies of HII region-molecular cloud interactions constrain models of feedback and quantify its impact on the surrounding environment. A recent hypothesis proposes t…
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…
New Interpretation for the Orientation of the LMC's Gaseous Arms B and E using ULLYSES
April Horton, Suraj Poudel, Kathleen A. Barger +20
The Large Magellanic Cloud (LMC) experiences disruption from tidal and ram-pressure forces as it travels through the halo of the Milky Way. In this project, we combine radio emissi…
A neutral hydrogen absorption study of cold gas in the outskirts of the Magellanic Clouds using the GASKAP-HI survey
Hongxing Chen, Snežana Stanimirović, Nickolas M. Pingel +18
Cold neutral hydrogen (HI) is a crucial precursor for molecular gas formation and can be studied via HI absorption. This study investigates HI absorption in low column density regi…
Considerations with stacking absorption spectra: cold HI gas in cirrus region of the Milky Way
Callum Lynn, Antoine Marchal, N. M. McClure-Griffiths +15
We use the Milky Way neutral hydrogen (HI) absorption and emission spectra from the Galactic Australian Square Kilometre Array Pathfinder (GASKAP) Phase II Pilot survey along with…
Processing of GASKAP-HI pilot survey data using a commercial supercomputer
Ian P. Kemp, Nickolas M. Pingel, Rowan Worth +15
Modern radio telescopes generate large amounts of data, with the next generation Very Large Array (ngVLA) and the Square Kilometre Array (SKA) expected to feed up to 292 GB of visi…
Nitric Oxide and other molecules: Molecular Modelling and Low FrequencyExploration using the Murchison Widefield Array
Chenoa D. Tremblay, Malcolm D. Gray, Natasha Hurley-Walker +6
We present new molecular modelling for 14NO and 15NO and a deep, blind molecular line survey at low radio frequencies (99-129 MHz). This survey is the third in a series completed w…
Calibrating the HISA temperature: Measuring the temperature of the Riegel-Crutcher cloud
H. Denes, N. M. McClure-Griffiths, J. M. Dickey +2
HI self absorption (HISA) clouds are clumps of cold neutral hydrogen (HI) visible in front of warm background gas, which makes them ideal places to study the properties of the cold…
SPLASH: The Southern Parkes Large-Area Survey in Hydroxyl - First Science from the Pilot Region
J. R. Dawson, A. J. Walsh, P. A. Jones +20
SPLASH (the Southern Parkes Large-Area Survey in Hydroxyl) is a sensitive, unbiased and fully-sampled survey of the Southern Galactic Plane and Galactic Centre in all four ground-s…
