Unveiling AGN Outflows: [O iii] Outflow Detection Rates and Correlation with Low-Frequency Radio Emission

Emmy L. Escott, Leah K. Morabito, Jan Scholtz +10

Some Active Galactic Nuclei (AGN) host outflows which have the potential to alter the host galaxy's evolution (AGN feedback). These outflows have been linked to enhanced radio emis…

Radio-AGN activity across the galaxy population: dependence on stellar mass, star-formation rate, and redshift

R. Kondapally, P. N. Best, K. J. Duncan +16

We characterise the co-evolution of radio-loud AGN and their galaxies by mapping the dependence of radio-loud AGN activity on stellar mass and star-formation rate (SFR) across cosm…

Galaxy Mergers in the Epoch of Reionization II: Major Merger-Triggered Star Formation and AGN Activities at 4.5-8.5

Qiao Duan, Qiong Li, Christopher J. Conselice +29

Galaxy mergers are a key driver of galaxy formation and evolution, including the triggering of AGN and star formation to a still unknown degree. We thus investigate the impact of g…
