We probe the atomic hydrogen (HI) emission from the host galaxies of fast radio bursts (FRBs) to investigate the emerging trend of disturbance and asymmetry in the population. Quad…
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…

We use HI data from the FAST Extended Atlas of Selected Targets Survey (FEASTS) to study the interplay between gas and star formation of galaxies in interacting systems. We build c…
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…
Low-Frequency Turnover Star Forming Galaxies I: Radio Continuum Observations and Global Properties
J. A. Grundy, N. Seymour, O. I. Wong +3
The broad-band radio spectral energy distribution (SED) of star-forming galaxies (SFGs) contains a wealth of complex physics. We aim to determine the physical emission and loss pro…
