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…
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…
Glance: A Comprehensive Framework for Galactic Archaeology
Iris Breda, Glenn van de Ven, Sabine Thater +8
A central topic in extragalactic astronomy is understanding the formation and evolutionary histories of galaxies. These systems often comprise multiple structural components with d…
The effect of extended radio emission on SMBH accretion rate estimates
Stergios Amarantidis, Duncan Farrah, Nick Seymour +5
Accretion rates in radio galaxies are typically estimated from optical and total radio flux measurements, incorporating emission from the core, jets, and lobes. These estimates can…
Unveiling faint X-ray AGN populations in the NewAthena era: Insights from cosmological simulations
Nuno Covas, Israel Matute, Stergios Amarantidis +7
Recent observations expanded our understanding of galaxy formation and evolution, yet key challenges persist in the X-ray regime, crucial for studying Active Galactic Nuclei (AGN).…
EMU/GAMA: A new approach to characterising radio luminosity functions
J. Prathap, A. M. Hopkins, J. Afonso +16
This study characterises the radio luminosity functions (RLFs) for SFGs and AGN using statistical redshift estimation in the absence of comprehensive spectroscopic data. Sensitive…
