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…

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…

WALLABY Pilot Survey: kNN identification of perturbed galaxies through HI morphometrics

B. W. Holwerda, Helga Dénes, J. Rhee +11

Galaxy morphology in stellar light can be described by a series of "non-parametric" or "morphometric" parameters, such as concentration-asymmetry-smoothness, Gini, , and Se…

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…

WALLABY Pilot Survey & ASymba: Comparing HI Detection Asymmetries to the SIMBA Simulation

Mathieu Perron-Cormier, Nathan Deg, Kristine Spekkens +15

An avenue for understanding cosmological galaxy formation is to compare morphometric parameters in observations and simulations of galaxy assembly. In this second paper of the ASym…
