题目：Co-evolution of Galaxies and Black Holes in the Early Universe with JWST

报告人：Dr. Jianwei Lyu（Steward Observatory, University of Arizona）

摘要：In this talk, I will provide a brief overview of key findings on high-redshift active galactic nuclei (AGN), including the properties of their host galaxies revealed by JWST observations, and discuss their broader implications. Highlights will include results from extensive follow-up observations of known bright quasars at cosmic dawn, as well as the new discovery of a large population of fainter and/or obscured AGN (including the so-called “little red dots”). These high-redshift AGN populations exhibit a variety of intriguing features, though their interpretation remains complex, with many unresolved questions. Notably, we are still far from having a complete picture of the AGN population at high redshift, and much work remains to be done, particularly with MIRI.
