Extended Radio Galaxies in EMU: A Comparative Look at Source-Finding Techniques
Lachlan J. Barnes, Andrew M. Hopkins, Yjan Gordon +8
Extended radio sources present unique challenges for automated detection and classification in wide-field radio surveys. With current surveys such as the Evolutionary Map of the Un…
Machine Learning Frameworks for Large-Scale Radio Surveys: A Summary of Recent Studies
Nikhel Gupta
The rapid growth of large-scale radio surveys, generating over 100 petabytes of data annually, has created a pressing need for automated data analysis methods. Recent research has…
Deep polarimetry study reveals double ring ORC-like structures
Sam Taziaux, Dominik J. Bomans, Christopher J. Riseley +10
New observations with the current generation of advanced radio interferometers, such as ASKAP and MeerKAT, have led to the discovery of new classes of extended radio sources of unk…
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…
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…
