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 (…
Revealing the magnetization of the intracluster medium of Abell 3581 using background Faraday rotation measures from the POSSUM survey
Affan Khadir, Erik Osinga, Wonki Lee +16
The line-of-sight magnetic field of galaxy clusters can be probed using Faraday rotation measure (RM) data. However, our understanding of cluster magnetism is limited due to the sc…
Magnetic Fields in the Shapley Supercluster Core with POSSUM: Challenging Model Predictions
D. Alonso-López, S. P. O'Sullivan, A. Bonafede +18
Faraday Rotation Measure (RM) Grids provide a sensitive means to trace magnetized plasma across a wide range of cosmic environments. We study the RM signal from the Shapley Supercl…
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…
Quantifying Radio Source Morphology
Lachlan J. Barnes, Andrew M. Hopkins, Lawrence Rudnick +6
The advent of next-generation telescope facilities brings with it an unprecedented amount of data, and the demand for effective tools to process and classify this information has b…
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…
