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 (…

Evolutionary Map of the Universe: A pilot survey to detect high Galactic latitude pulsars in variance images with ASKAP

A. Ahmad, S. Dai, E. Lenc +13

It has been proposed that radio pulsars can be distinguished from other point-like radio sources in continuum images by their unique interstellar scintillation signatures. Using da…

Evolutionary Map of the Universe (EMU): a pilot search for diffuse, non-thermal radio emission in galaxy clusters with the Australian SKA Pathfinder

S. W. Duchesne, A. Botteon, B. S. Koribalski +10

Clusters of galaxies have been found to host Mpc-scale diffuse, non-thermal radio emission in the form of central radio halos and peripheral relics. Turbulence and shock-related pr…

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…
