Summary talk on the Topic 1, AGN Population and BH-Host Scaling Relations.
The James Webb Space Telescope (JWST) has opened a new window into the early universe, providing unparalleled insights into the population of high-redshift, low-luminosity active galactic nuclei (AGNs), including a new class of objects known as Little Red Dots (LRDs). These objects have significant implications for a range of topics, from the formation mechanisms of supermassive black holes (BHs) and BH-galaxy coevolution to cosmic reionization and beyond. However, measuring the basic properties (e.g., bolometric luminosity, black hole mass, and host mass) of high-redshift AGNs remains a challenging task. Through the six talks within Topic 1: AGN Population and BH-Host Scaling Relations, we delved deeply into these subjects, highlighting key advancements and ongoing issues. In this talk, I will summarize the main points of these talks and discuss the unresolved challenges. Finally, I will discuss how forthcoming surveys with instruments like the China Space Station Telescope (CSST) can help to address these issues.
