Multiphase gas offsets in the atmospheres of central galaxies and their consequences for SMBH activation I. The hot and warm ionized gas phases
Francesco Ubertosi, Fabrizio Brighenti, Ewan O'Sullivan +10
We investigate the spatial relationships between multi-phase gas components and supermassive black hole (SMBH) activity in a sample of 25 cool core galaxy groups and clusters. Usin…

Probing the high frequency variability of NGC 5044: the key to AGN feedback
Gerrit Schellenberger, Ewan O'Sullivan, Laurence David +10
The active galactic nucleus (AGN) feeding and feedback process in the centers of galaxy clusters and groups is still not well understood. NGC 5044 is the ideal system in which to s…
