Why and when is internally-driven AGN feedback energetically favoured?
Edward C. D. Pope
AGN outflows are the heat given up when gas in a galaxy evolves towards thermodynamic equilibrium. Indeed, while AGN feedback regulates the growth of massive galaxies, its origins…
Investigating the properties of AGN feedback in hot atmospheres triggered by cooling-induced gravitational collapse
Edward C. D. Pope, J. Trevor Mendel, Stanislav S. Shabala
Radiative cooling may plausibly cause hot gas in the centre of a massive galaxy, or galaxy cluster, to become gravitationally unstable. The subsequent collapse of this gas on a dyn…
Investigating a model of optimised AGN feedback
Edward C. D. Pope
Feedback heating from AGN in massive galaxies and galaxy clusters can be thought of as a naturally occurring control system which plays a significant role in regulating both star f…
Mass transport by buoyant bubbles in galaxy clusters
Edward C. D. Pope, Arif Babul, Georgi Pavlovski +2
We investigate the effect of three important processes by which AGN-blown bubbles transport material: drift, wake transport and entrainment. The first of these, drift, occurs becau…
On the exclusion of intra-cluster plasma from AGN-blown bubbles
Edward C. D. Pope
Simple arguments suggest that magnetic fields should be aligned tangentially to the surface of an AGN-blown bubble. If this is the case, charged particles from the fully ionised in…
Stochastic heating of cooling flows
Georgi Pavlovski, Edward C. D. Pope
It is generally accepted that the heating of gas in clusters of galaxies by active galactic nuclei (AGN) is a form of feedback. Feedback is required to ensure a long term, sustaina…
