Supermassive Black Hole Feeding and Feedback in Massive Systems


Supermassive black holes (SMBHs) play a crucial role in shaping the evolution of galaxies, especially the massive ones. In this talk, I will briefly review our current knowledge of three key aspects of SMBHs -- their feeding, feedback, and connections to host galaxies. I will discuss some of the efforts my group has made to advance our understanding in these research areas. In particular, I will highlight our recent "mesoscale" simulations which follow multiphase SMBH accretion flows from galaxy scales all the way down to scales relevant for accretion disks. I will also discuss our recent observational analysis of the turbulent motion of the cool clouds in centers of galaxy clusters, which has significant implications on how SMBH feedback operates in these systems. The results also put unprecedented constraints on microscopic transport processes in the weakly collisional, magnetized intracluster plasma. I will also discuss some recent and ongoing work on SMBH-host galaxy scaling relations and how machine learning may transform this field. Lastly, I will briefly discuss some exciting future directions of my research program.
