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…
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…
Murriyang cryogenic phased array feed: spectral-line results and noise-reduction methods
L. Staveley-Smith, S. Barker, R. Berangi +25
Spectral-line results from a new cryogenic phased array feed (cryoPAF) on the Murriyang telescope at Parkes are presented. This array offers a significant improvement in field of v…
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…
WALLABY pilot survey: properties of HI-selected dark sources and low surface brightness galaxies
T. O'Beirne, L. Staveley-Smith, V. A. Kilborn +13
We examine the optical counterparts of the 1829 neutral hydrogen (HI) detections in three pilot fields in the Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) using dat…
