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…

Multi-frequency radio-continuum study of the LMC SNR N206 (Goat's Eye) and its "zig-zag" PWN

M. Ghavam, Z. J. Smeaton, M. D. Filipovic +17

We present new radio-continuum observations of the Large Magellanic Cloud (LMC) supernova remnant (SNR) N206, which we give the name "Goat's Eye". Goat's Eye contains an interior r…

New ASKAP radio-continuum surveys of the Small Magellanic Cloud

O. K. Khattab, M. D. Filipovic', Z. J. Smeaton +5

We present two new radio continuum images from the ASKAP POSSUM survey in the direction of the Small Magellanic Cloud. The two new source lists contain 36,571 radio continuum sourc…

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…

EMU and the DRAGNs I: A Catalogue of DRAGNs

Ray P. Norris, Miranda Yew, Evan Crawford +10

We present a catalogue of 3557 Double Radio sources associated with Active Galactic Nuclei (DRAGNs) from the First Pilot Survey of the Evolutionary Map of the Universe (EMU), obser…

Study of a giant Large Magellanic Cloud Supernova Remnant, Veliki (J0450.4-7050)

Z. J. Smeaton, M. D. Filipović, R. Z. E. Alsaberi +12

We present a high-resolution radio-continuum view and a multi-frequency analysis of the Large Magellanic Cloud (LMC) Supernova Remnant (SNR) J0450.4-7050, which we give the nicknam…
