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 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…

GTC Spectroscopic Surveys of Planetary Nebulae in the Milky Way and M31

Xuan Fang, Haomiao Huang, Martin A. Guerrero +4

We report spectroscopic surveys of planetary nebulae (PNe) in the Milky Way and Andromeda (M31), using the 10.4-m Gran Telescopio Canarias (GTC). The spectra are of high quality an…

HI filaments as potential compass needles? Comparing the magnetic field structure of the Small Magellanic Cloud to the orientation of GASKAP-HI filaments

Y. K. Ma, N. M. McClure-Griffiths, S. E. Clark +12

High-spatial-resolution HI observations have led to the realisation that the nearby (within few hundreds of parsecs) Galactic atomic filamentary structures are aligned with the amb…

Discovery of a filamentary synchrotron structure connected to the coherent magnetic field in the outer Galaxy

J. L. West, J. L. Campbell, P. Bhaura +9

Using data from the Galactic Arecibo L-band Feed Array Continuum Transit Survey (GALFACTS), we report the discovery of two previously unidentified, very compressed, thin, and strai…
