Deep ASKAP EMU Survey of the GAMA23 field: Properties of radio sources
Gülay Gürkan, I. Prandoni, A. O'Brien +19
We present the Australian Square Kilometre Array Pathfinder (ASKAP) observations of the Galaxy and Mass Assembly (GAMA)-23h field. The survey was carried out at 887.5 MHz and cover…
Remnant Radio Galaxies Discovered in a Multi-frequency Survey
B. Quici, N. Hurley-Walker, N. Seymour +20
The remnant phase of a radio galaxy begins when the jets launched from an active galactic nucleus are switched off. To study the fraction of radio galaxies in a remnant phase, we t…
Unexpected Circular Radio Objects at High Galactic Latitude
Ray P. Norris, Huib T. Intema, Anna D. Kapinska +26
We have found a class of circular radio objects in the Evolutionary Map of the Universe Pilot Survey, using the Australian Square Kilometre Array Pathfinder telescope. The objects…
PKS 2250351: A Giant Radio Galaxy in Abell 3936
N. Seymour, M. Huynh, S. S. Shabala +27
We present a detailed analysis of the radio galaxy PKS 2250-351, a giant of 1.2 Mpc projected size, its host galaxy, and its environment. We use radio data from the Murchison Widef…
The Spatial Correlation of Bent-Tail Galaxies and Galaxy Clusters
Andrew N. O'Brien, Ray P. Norris, Nick F. H. Tothill +1
We have completed a deep radio continuum survey covering 86 square degrees of the Spitzer-South Pole Telescope deep field to test whether bent-tail galaxies are associated with gal…
High-resolution Observations of Low-luminosity Gigahertz-Peaked Spectrum and Compact Steep Spectrum Sources
Jordan D. Collier, Steven J. Tingay, Joseph R. Callingham +27
We present Very Long Baseline Interferometry observations of a faint and low-luminosity ($L_{\rm 1.4 GHz} < 10^{27}~\mbox{W Hz}^{-1}$) Gigahertz-Peaked Spectrum (GPS) and Compact S…
A Multi-Frequency Study of the Milky Way-like Spiral Galaxy NGC 6744
Miranda Yew, Miroslav D. Filipović, Quentin Roper +14
We present a multi-frequency study of the intermediate spiral SAB(r)bc type galaxy NGC 6744, using available data from the Chandra X-Ray telescope, radio continuum data from the Au…
Sub-kiloparsec Imaging of Cool Molecular Gas in Two Strongly Lensed Dusty, Star-Forming Galaxies
J. S. Spilker, M. Aravena, D. P. Marrone +20
We present spatially-resolved imaging obtained with the Australia Telescope Compact Array (ATCA) of three CO lines in two high-redshift gravitationally lensed dusty star-forming ga…
Radio-Continuum Study of the Nearby Sculptor Group Galaxies. Part 3: NGC 7793 at lambda=12.2, 6 and 3 cm
Timothy J. Galvin, Miroslav D. Filipović, Nicholas F. H. Tothill +6
We re-examine a series of archived centimetre radio-continuum observations (lambda=16, 6 and 3 cm) focusing on NGC7793 using the Australia Telescope Compact Array. These new images…
