Seminar:- AGN Feedback in Galaxy Clusters and Our Galaxy
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. Active Galactic Nucleus(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, the speaker will present his recent work on the physics and impact of jet-mode AGN feedback in galaxy clusters. He will also briefly discuss the physics of Fermi bubbles in the Milky Way with a focus on our AGN jet model.
