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…
Gas-rich dwarf galaxy multiples in the Apertif HI survey
B. Šiljeg, E. A. K. Adams, F. Fraternali +8
Dwarf-dwarf galaxy encounters are a key aspect of galaxy evolution as they can ignite or temporarily suppress star formation in dwarfs and can lead to dwarf mergers. However, the f…
Testing OH Megamaser Identification Methods in HI Surveys: Updated Source-Flagging Algorithms and New Detections in ALFALFA
Hayley Roberts, Jeremy Darling, Kelley M. Hess +3
OH megamasers (OHMs) are extragalactic masers found primarily in gas-rich galaxy major mergers. To date, only 120 OHMs have been cataloged since their discovery in 1982, and…
WALLABY pilot survey: Spatially resolved gas scaling relations within the stellar discs of nearby galaxies
Seona Lee, Barbara Catinella, Tobias Westmeier +13
The scatter in global atomic hydrogen (HI) scaling relations is partly attributed to differences in how HI and stellar properties are measured, with HI reservoirs typically extendi…

The data volumes generated by the WALLABY atomic Hydrogen (HI) survey using the Australiian Square Kilometre Array Pathfinder (ASKAP) necessitate greater automation and reliable au…
A Galactic Eclipse: The Small Magellanic Cloud is Forming Stars in Two, Superimposed Systems
Claire E. Murray, Sten Hasselquist, Joshua E. G. Peek +22
The structure and dynamics of the star-forming disk of the Small Magellanic Cloud (SMC) have long confounded us. The SMC is widely used as a prototype for galactic physics at low m…
WALLABY Pilot Survey: The diversity of HI structural parameters in nearby galaxies

Combining new HI data from a synergetic survey of ASKAP WALLABY and FAST with the ALFALFA data, we study the effect of ram pressure and tidal interactions in the NGC 4636 group. We…
WALLABY Pilot Survey: Hydra Cluster Galaxies UV and HI morphometrics
Benne W. Holwerda, Frank Bigiel, Albert Bosma +16
Galaxy morphology in atomic hydrogen (HI) and in the ultra-violet (UV) are closely linked. This has motivated their combined use to quantify morphology over the full H i disk for b…
