Bridging the mass gap: Diffuse radio emission in GAMA galaxy groups using EMU and DINGO survey data
Sai Wagh, Tessa Vernstrom, Luke J. M. Davies +11
The study uses deep radio data from the EMU and DINGO surveys to search for and characterize diffuse, low‑surface‑brightness radio emission in 400 low‑redshift galaxy groups, findi…
MIGHTEE-HI: HI catalogue of 293 sources for the COSMOS field and comparative study of 3-dimensional source finding methods
Michalina Maksymowicz-Maciata, Natasha Maddox, Catherine Hale +12
We present a catalogue of HI sources extracted from the MIGHTEE survey data cubes covering the COSMOS field. The catalogue contains 293 sources in the redshift range of 0.004 < z <…
DINGO/GAMA /WAVES: HI-halo mass relation
Ajay Dev, Martin Meyer, Simon P. Driver +17
We investigate the relation between neutral atomic hydrogen (HI) and dark matter halo mass (HIHM) using observations from the Deep Investigation of Neutral Gas Origins (DINGO) pilo…
WALLABY pilot survey: HI depletion times within the stellar discs of nearby galaxies
Seona Lee, Barbara Catinella, Tobias Westmeier +12
Neutral atomic hydrogen (HI) reservoirs typically extend far beyond the inner star-forming regions of galaxies, and global HI measurements, which mix these distinct environments, l…
WALLABY pilot survey: Blinded by the light -- discovery of a fourth member in the ESO 179-013 system
Rayssa Guimarães Silva, Marco Grossi, Denise R. Gonçalves +12
We present new ASKAP/WALLABY HI observations of the nearby dwarf galaxy system ESO 179-013 (Kathryn's Wheel), the nearest known collisional ring galaxy, located 10 Mpc away in the…
Deep Investigation of Neutral Gas Origins (DINGO): Options for robust Deep Spectral Line Imaging in the SKA-Era
Jonghwan Rhee, Richard Dodson, Alexander Williamson +8
The data storage requirements for deep spectral line observations with next-generation radio interferometers like the Australian Square Kilometre Array Pathfinder (ASKAP) and the S…
