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 understand 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.


Before joining Peking University, Kavli Institute for Astronomy and Astrophysics in 2018 fall, Dr. Inayoshi spent 4 years at Columbia University in the US as a Junior Simons Fellow. He received his Ph.D. in physics from Kyoto University, Japan, in 2014. He is interested in a variety of topics on the physics of black holes, including gas accretion physics, formation of supermassive black holes, and multi-frequency gravitational wave astronomy.Dr. Inayoshi was awarded the "Young Astronomer Prize of 2021" from the Astronomical Society of Japan for his research on “theoretical studies for the formation and evolution of massive black holes”.
