ALMA reveals a compact and massive molecular outflow driven by the young AGN in a nearby ULIRG

Luke R. Holden, Clive N. Tadhunter, Anelise Audibert +5

The ultra luminous infrared galaxy (ULIRG) F13451+1232 is an excellent example of a galaxy merger in the early stages of active galactic nucleus (AGN) activity, a phase in which AG…

Scrutinising evidence for the triggering of Active Galactic Nuclei in the outskirts of massive galaxy clusters at

Iván Muñoz Rodríguez, Antonis Georgakakis, Francesco Shankar +6

Environmental effects are believed to play an important yet poorly understood role in triggering accretion events onto the supermassive black holes (SMBHs) of galaxies (Active Gala…

A post-merger enhancement only in star-forming Type 2 Seyfert galaxies: the deep learning view

M. S. Avirett-Mackenzie, C. Villforth, M. Huertas-Company +7

Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major mergers have the ab…
