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…

Local HI Absorption towards the Magellanic Cloud foreground using ASKAP

Hiep Nguyen, N. M. McClure-Griffiths, James Dempsey +21

We present the largest Galactic neutral hydrogen HI absorption survey to date, utilizing the Australian SKA Pathfinder Telescope at an unprecedented spatial resolution of 30''. Thi…

Galactic Small Scale Structure Revealed by the GALFA-HI Survey

Ayesha Begum, Snezana Stanimirovic, Joshua E. Peek +10

The Galactic Arecibo L-band Feed Array HI (GALFA-HI) survey is mapping the entire Arecibo sky at 21-cm, over a velocity range of -700 to +700 km/s (LSR), at a velocity resolution o…

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…

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…
