The Road to Identifying the Earliest Radio-Powerful AGN with the SKA
Jose Afonso, Stergios Amarantidis, Stas Shabala +20
The Epoch of Reionization (EoR) is one of the most pivotal frontiers in modern astrophysics, marking the emergence of the first galaxies, stars, and supermassive black holes (SMBHs…
Radio Galaxies and Jet Duty Cycles
M. J. Hardcastle, C. Konar, S. Dutta +10
Radio-luminous active galactic nuclei, or radio galaxies, are the brightest population of objects in the extragalactic radio sky and will be seen in large numbers in essentially ev…
Compact radio galaxies: the case of FR0s
R. D. Baldi, A. Capetti, G. Giovannini +20
Fanaroff-Riley type 0 (FR0) radio galaxies, a newly-identified and abundant population of low-power radio-loud active galactic nuclei, present a significant challenge to our unders…
Evolution of AGN Across Cosmic Epochs with the SKAO
R. Kondapally, V. Singh, G. Mazzolari +10
Understanding the evolution of active galactic nuclei (AGN) and their host galaxies across cosmic epochs is one of the key science drivers of extragalactic astronomy. The detection…
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…
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,…
