WALLABY Pilot Survey: the Potential Polar Ring Galaxies NGC~4632 and NGC~6156

N. Deg, R. Palleske, K. Spekkens +24

We report on the discovery of two potential polar ring galaxies (PRGs) in the WALLABY Pilot Data Release 1 (PDR1). These untargetted detections, cross-matched to NGC 4632 and NGC 6…

Collimation of the kiloparsec-scale radio jets in NGC 2663

Velibor Velović, M. D. Filipović, L. Barnes +25

We present the discovery of highly-collimated radio jets spanning a total of 355 kpc around the nearby elliptical galaxy NGC 2663, and the possible first detection of recollimation…

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…
