HI rotation curves and mass-size relation for 568 galaxies from the Apertif Wide-area Extragalactic Survey

Konstantin Haubner, Federico Lelli, Enrico Di Teodoro +13

The extended HI rotation curves of galaxies are one of the most powerful tools for studying galaxy evolution and for testing different dark matter and modified gravity models. Howe…

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…

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…

The mystery of extremely HI rich galaxies

H. Denes, V. A. Capa

The properties of galaxies follow scaling relations related to the physics that govern galaxy evolution. Based on these, we can identify galaxies undergoing specific evolutionary p…

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…

A new method for spatially resolving the turbulence driving mixture in the ISM with application to the Small Magellanic Cloud

Isabella A. Gerrard, Christoph Federrath, Nickolas M. Pingel +12

Turbulence plays a crucial role in shaping the structure of the interstellar medium. The ratio of the three-dimensional density contrast () to the turbulent sonic Mach n…

Structure and kinematics of shocked gas in Sgr B2: further evidence of a cloud-cloud collision from SiO emission maps

Jairo Armijos-Abendaño, Wladimir Banda-Barragán, Jesús Martín-Pintado +3

We present SiO J=2-1 maps of the Sgr B2 molecular cloud, which show shocked gas with a turbulent substructure comprising at least three cavities at velocities of [10,40] km s$^{-1}…
