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…
The Salamander: A case study of the magnetic field and peculiar morphology of G309.8-2.6 through radio polarimetry
Wenhui Jing, Jennifer L. West, Xiaohui Sun +17
Studying the interaction between core-collapse supernova remnants (SNRs) and their surrounding environments is essential to understanding the mechanism for energy transfer to the i…
EMU Radio Observations of Barred Spiral Galaxy NGC 5938 (Araish)
H. Zakir, M. D. Filipović, L. Barnes +14
We present multi-wavelength observations of the nearby spiral galaxy NGC 5938 (Araish) to investigate the origin of its radio emission, specifically the contribution from active ga…
MeerKAT discovery of 164 compact radio rings toward the Galactic Plane
C. Bordiu, F. Bufano, G. Umana +14
We report the discovery of 164 compact (radius < 1 arcmin) radio rings using MeerKAT 1.3 GHz data from the SARAO MeerKAT Galactic Plane Survey (l=2-60deg, 252-358deg, |b|<1.5deg) a…
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…
Discovery of Odd Radio Circles and Other Peculiars in the First Year of the EMU Survey using Object Detection
Nikhel Gupta, Ray P. Norris, Zeeshan Hayder +9
We present a systematic search for Odd Radio Circles (ORCs) and other unusual radio morphologies using data from the first year of the EMU (Evolutionary Map of the Universe) survey…
The Jet Paths of Radio AGN and their Cluster Weather
E. Vardoulaki, V. Backöfer, A. Finoguenov +21
We studied bent radio sources within X-ray galaxy groups in the COSMOS and XMM-LSS fields, using radio data from the MeerKAT International GHz Tiered Extragalactic Explorations dat…
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…
