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…

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…

ASKAP reveals the radio tail structure of the Corkscrew Galaxy shaped by its passage through the Abell 3627 cluster

Bärbel S. Koribalski, Stefan W. Duchesne, Emil Lenc +12

Among the bent tail radio galaxies common in galaxy clusters are some with long, collimated tails (so-called head-tail galaxies) shaped by their interactions with the intracluster…

The Physalis system: Discovery of ORC-like radio shells around a massive pair of interacting early-type galaxies with offset X-ray emission

Bärbel S. Koribalski, Ildar Khabibullin, Klaus Dolag +7

We present the discovery of large radio shells around a massive pair of interacting galaxies and extended diffuse X-ray emission within the shells. The radio data were obtained wit…
