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…
Through the fog: a complementary optical galaxy classification scheme for 'intermediate' redshifts
Duarte Muñoz Santos, Cirino Pappalardo, Henrique Miranda +10
Understanding galaxy classification depends on our interpretation of their spectra. To date, the hydrogen Balmer lines remain the most consistent way to classify galaxies, but at '…
Importance of modelling the nebular continuum in galaxy spectra
Henrique Miranda, Ciro Pappalardo, José Afonso +7
The neglect of modelling both stellar and nebular emission significantly affects the derived physical properties of galaxies, particularly those with high star formation rates. Whi…
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).…
