简介: |
The astonishing phenomena of AGN feedback eject a tremendous amount of energy and possibly momentum into their environs, and are commonly believed to play a key role in cosmic structure evolution. AGN feedback has thus received a lot of attention in the last decades, and yet poses one of the central unsolved problems in contemporary astronomy. Is it really responsible for star formation quenching in galaxies? How do AGN feedback events transfer energy to their hosting galaxies and clusters? In this talk, I will discuss radio-mode AGN feedback in galaxy clusters and the Fermi bubbles in the Milky Way, two observationally-different (but analogous) events both likely related to AGN jets, and potentially producing different effects in two very different environments.
Bio: Prof. Fulai Guo is a faculty member in the astrophysics division of Shanghai Astronomical Observatory, currently setting up the Black Hole Feedback and Cosmic Ray Astrophysics research group. He received his B.S. degree in astrophysics from University of Science and Technology of China, and a PhD in Physics from University of California, Santa Barbara. He was then a postdoctoral scholar at University of California, Santa Barbara, and at UCO/Lick Observatory at University of California, Santa Cruz, and more recently a Zwicky prize fellow at Swiss Federal Institute of Technology Zurich. His research interests include AGN feedback, the Fermi bubbles, cosmic ray astrophysics, numerical simulations, galaxy quenching, dark matter distributions and signatures, etc.
