ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)

M. D. Filipović, Z. J. Smeaton, A. C. Bradley +33

We report diffuse extended radio-continuum emission spatially coinciding with the IR source WISEA J094409.17-751012.8, and a semi-variable star, V687 Carinae. We use 944 MHz radio…

Stingrays in the radio sky: Two unusual diffuse radio relic sources in the direction of the Magellanic Stream

Zachary J Smeaton, Miroslav D Filipovic, Barbel S Koribalski +17

We present the discovery of two extended, low surface brightness radio continuum sources, each consisting of a near-circular body and an extended tail of emission, nicknamed Stingr…

MeerKAT discovery of a MIGHTEE Odd Radio Circle

Ray P. Norris, Bärbel S. Koribalski, Catherine L. Hale +3

We present the discovery of a new Odd Radio Circle (ORC J0219--0505) in 1.2~GHz radio continuum data from the MIGHTEE survey taken with the MeerKAT telescope. The radio-bright host…

COALAS III: The ATCA CO(1-0) look at the growth and death of H emitters in the Spiderweb protocluster at z=2.16

J. M. Pérez-Martínez, H. Dannerbauer, B. H. C. Emonts +26

We obtain CO(1-0) molecular gas measurements with ATCA on a sample of 43 spectroscopically confirmed H emitters in the Spiderweb protocluster at and investigate the re…

Evolutionary Map of the Universe (EMU): Observations of Filamentary Structures in the Abell S1136 Galaxy Cluster

Peter. J. Macgregor, Ray P. Norris, Andrew O'Brien +17

We present radio observations of the galaxy cluster Abell S1136 at 888 MHz, using the Australian Square Kilometre Array Pathfinder radio telescope, as part of the Evolutionary Map…
