The Age of Discovery with JWST: Excavating the First Massive Black Holes and First Galaxies

要旨
The James Webb Space Telescope (JWST) is opening a new window of the most distant universe and will unveil the early growth of supermassive black holes (BHs) in the first galaxies. The existence of supermassive massive BHs observed when the universe was younger than one billion years strongly constrains their formation pathway and provides a crucial hint to understanding the coevolution between BHs and galaxies. In this talk, I will review the physical mechanisms that promote rapid assembly and growth of seed BHs in early protogalaxies and discuss how JWST will probe the earliest structure formation in the near future.
