Early JWST View of High-Redshift Quasars

Quasars at cosmic dawn are powerful probes to the formation and growth of early supermassive black holes in the universe, their connections to high-redshift galaxy and structure formation, and the evolution of the intergalactic medium at the epoch of reionization. I will present early JWST results of high-redshift quasars and their environments from JWST programs targeting about qusars at z~7. The diverse quasar environment unveiled by these observations suggests a complex interplay between black hole accretion, galaxy assembly, the physics of reionization and the emergence of early large scale structure.
