Nuclear and Star Formation Activities: Roles of Gas Supply and Active Galactic Nucleus Feedback

Speaker: Huynh Anh N. Le (USTC)

Venue: SWIFAR Building 2111

Time: 12:45 PM, Monday, Mar. 31, 2025

Abstract: 

The mass of black holes (BHs) is a crucial parameter for understanding the coevolution of BHs and their host galaxies. However, the estimation of BH masses still suffers from significant uncertainty, particularly for high-redshift Active Galactic Nuclei (AGNs), across various methods. To fully understand the coevolution between BHs and their host galaxies, it is necessary to utilize deep and high-quality spectroscopic data covering a broad wavelength range to probe the activities and growth of BHs and their host galaxies. In this talk, I will present some of our recent works related to this topic. I will first present the improvement in single-epoch BH mass measurement. Then, I will talk about the gas kinematic properties of both broad- and narrow-line regions, as well as the stellar host properties associated with these AGNs. Lastly, I will discuss the role of gas supply and AGN (jet) feedback in shaping AGN and/or galaxy evolution.
