Description

Title: AGN feedback on Bulge’s dynamics

 
Abstract:
 It is well known that Active Galactic Nuclei (AGN) has feedback on galaxies. Previous studies have often focused on gas dynamics and star formation rates in galaxies. However, the kinematics of stars can also be influenced by the feedback processes. In this talk, we will primarily focus on the impact of massive, fast outflows on the dynamics of galactic bulges. We consider both the changes in gravitational potential induced by gas motion and the effects of stellar encounters. Our preliminary findings reveal that the bulge exhibits quasi-periodic radial oscillations, in response to AGN’s activity.
