Early Science from POSSUM: Shocks, turbulence, and a massive new reservoir of ionised gas in the Fornax cluster
C. S. Anderson, G. H. Heald, J. A. Eilek +19
We present the first Faraday rotation measure (RM) grid study of an individual low-mass cluster -- the Fornax cluster -- which is presently undergoing a series of mergers. Exploiti…
An ASKAP survey for HI absorption towards dust-obscured quasars
M. Glowacki, J. R. Allison, V. A. Moss +11
Obscuration of quasars by accreted gas and dust, or dusty intervening galaxies, can cause active galactic nuclei (AGN) to be missed in optically-selected surveys. Radio observation…
The extraordinary linear polarisation structure of the southern Centaurus A lobe revealed by ASKAP
Craig S. Anderson, George Heald, Shane P. O'Sullivan +14
We present observations of linear polarisation in the southern radio lobe of Centaurus A, conducted during commissioning of the Australian Square Kilometre Array Pathfinder (ASKAP)…
On the dynamics of the Small Magellanic Cloud through high-resolution ASKAP HI observations
E. M. Di Teodoro, N. M. McClure-Griffiths, K. E. Jameson +10
We use new high-resolution HI data from the Australian Square Kilometre Array Pathfinder (ASKAP) to investigate the dynamics of the Small Magellanic Cloud (SMC). We model the HI ga…
Cold gas outflows from the Small Magellanic Cloud traced with ASKAP
N. M. McClure-Griffiths, H. Dénes, J. M. Dickey +19
Feedback from massive stars plays a critical role in the evolution of the Universe by driving powerful outflows from galaxies that enrich the intergalactic medium and regulate star…
WALLABY Early Science - I. The NGC 7162 Galaxy Group
Tristan N. Reynolds, Tobias Westmeier, Lister Staveley-Smith +21
We present Widefield ASKAP L-band Legacy All-sky Blind Survey (WALLABY) early science results from the Australian Square Kilometre Array Pathfinder (ASKAP) observations of the NGC…
Connecting X-ray absorption and 21cm neutral hydrogen absorption in obscured radio AGN
V. A. Moss, J. R. Allison, E. M. Sadler +22
Many radio galaxies show the presence of dense and dusty gas near the active nucleus. This can be traced by both 21cm HI absorption and soft X-ray absorption, offering new insight…
Illuminating the past 8 billion years of cold gas towards two gravitationally lensed quasars
J. R. Allison, V. A. Moss, J. -P. Macquart +15
Using the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (ASKAP BETA), we have carried out the first survey for HI and OH absorptio…
The radio spectral energy distribution of infrared-faint radio sources
A. Herzog, R. P. Norris, E. Middelberg +57
Infrared-faint radio sources (IFRS) are a class of radio-loud (RL) active galactic nuclei (AGN) at high redshifts (z > 1.7) that are characterised by their relative infrared faintn…
High-velocity OH megamasers in IRAS 20100-4156: Evidence for a Supermassive Black Hole
L. Harvey-Smith, J. R. Allison, J. A. Green +14
We report the discovery of new, high-velocity narrow-line components of the OH megamaser in IRAS 20100-4156. Results from the Australian Square Kilometre Array Pathfinder (ASKAP)'s…
ASKAP HI imaging of the galaxy group IC 1459
P. Serra, B. Koribalski, V. Kilborn +76
We present HI imaging of the galaxy group IC 1459 carried out with six antennas of the Australian SKA Pathfinder equipped with phased-array feeds. We detect and resolve HI in eleve…
Discovery of HI gas in a young radio galaxy at using the Australian Square Kilometre Array Pathfinder
J. R. Allison, E. M. Sadler, V. A. Moss +100
We report the discovery of a new 21-cm HI absorption system using commissioning data from the Boolardy Engineering Test Array of the Australian Square Kilometre Array Pathfinder (A…
