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…
The GLEAM 4-Jy (G4Jy) Sample: IV. Multiwavelength data and analysis
Sarah V. White, Precious K. Sejake, Kshitij Thorat +17
We provide an updated 'multiwavelength' version of the G4Jy catalogue (available at https://github.com/svw26/G4Jy, https://zenodo.org/communities/g4jy/records, and through VizieR),…
Here Be SDRAGNs - Spiral Galaxies Hosting Large Double Radio Sources
Jean Tate, William C. Keel, Michael O'Keeffe +16
We present a sample of large double radio sources hosted by spiral galaxies (Spiral Double Radio Active Galactic Nuclei, SDRAGNs). Candidates were selected during Radio Galaxy Zoo,…
The GLEAM 4-Jy (G4Jy) Sample: III. Further host-galaxy identification, and redshift assessment
Sarah V. White, Precious K. Sejake, Kshitij Thorat +17
In this paper we present 127 new host-galaxy identifications for G4Jy sources (S_151MHz > 4 Jy), based on radio images from MeerKAT, the Very Large Array Sky Survey (VLASS), and th…
Searching for the Largest Radio Galaxies
Heinz Andernach
The origins of radio astronomy and the discovery of the first radio galaxies are described which showed that the radio emission of active galaxies is very diverse in shape and can…
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…
