Odd radio circle J1555+2726: Observational evidence for shock re-acceleration of fossil plasma
L. Bruno, B. Koribalski, R. P. Norris +7
Context. Odd radio circles (ORCs) are peculiar extragalactic sources recently discovered. They are characterised by one or more bright rings extending on scales of hundreds of kilo…
Helical radio jets as probes of magnetised cluster environments: Periodic Faraday Rotation Revealed in the Corkscrew Galaxy by POSSUM
Sarah N. Bradbury, C. S. Anderson, N. M. McClure-Griffiths +14
Jets from active galactic nuclei (AGN) that exhibit regular plane-of-sky oscillations may provide a probe of magnetised plasma within the jets and their local intracluster medium (…
The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky
A. M. Hopkins, A. Kapinska, J. Marvil +70
We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas…
ASKAP Discoveries of Giant Radio Galaxies in the Sculptor field
B. S. Koribalski
We present the discovery of 15 well-resolved giant radio galaxies (GRGs) with angular sizes >5 arcmin and physical sizes >1 Mpc in wide-field Phased Array Feed 944 MHz observations…
Relighting the fire in Hickson Compact Group (HCG) 15: magnetised fossil plasma revealed by the SKA Pathfinders & Precursors
C. J. Riseley, T. Vernstrom, L. Lovisari +26
In the context of the life cycle and evolution of active galactic nuclei (AGN), the environment plays an important role. In particular, the over-dense environments of galaxy groups…
ASKAP EMU Radio Detection of the Reflection Nebula VdB-80 in the Monoceros Crossbones Filamentary Structure
A. C. Bradley, Z. J. Smeaton, N. F. H. Tothill +9
We present a new radio detection from the Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of the Universe (EMU) survey associated with the reflection nebula (…
MeerKAT reveals a ghostly thermal radio ring towards the Galactic Centre
C. Bordiu, M. D. Filipovic, G. Umana +26
We present the serendipitous discovery of a new radio-continuum ring-like object nicknamed Kyklos (J1802-3353), with MeerKAT UHF and L-band observations. The radio ring, which rese…
MeerKAT uncovers the physics of an Odd Radio Circle
Ray P. Norris, J. D. Collier, Roland M. Crocker +14
Odd Radio Circles (ORCs) are recently-discovered faint diffuse circles of radio emission, of unknown cause, surrounding galaxies at moderate redshift ($z ~ 0.2-0.6). Here we presen…
