Abstract
The astonishing phenomena of active galactic nucleus feedback have received a lot of attention in the literature, and yet pose one of the central unsolved problems in contemporary astronomy. AGN feedback events deposit a tremendous amount of energy into their host systems, and are commonly believed to play a key role in cosmic structure evolution. One of the most compelling evidence for AGN feedback comes from numerous detections of X-ray cavities and shock waves in galaxy clusters, apparently evolved from the interaction of AGN radio jets with the intracluster medium. In this talk, I will present my recent work on the physics and impact of jet-mode AGN feedback in galaxy clusters. I will also briefly discuss the physics of Fermi bubbles in the Milky Way with a focus on our AGN jet model.
Anyone interested is welcome to attend.
