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…
Experiences of Commercial Supercomputing in Radio Astronomy Data Processing
Ian Kemp, Steven J Tingay, Stuart Midgley +1
The ongoing exponential growth of computational power, and the growth of the commercial High Performance Computing (HPC) industry, has led to a point where ten commercial systems c…
A neutral hydrogen absorption study of cold gas in the outskirts of the Magellanic Clouds using the GASKAP-HI survey
Hongxing Chen, Snežana StanimiroviÄ, 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…
