Seeking the growth of the first black hole seeds with JWST

ABSTRACT In this paper, we provide predictions for the black hole (BH) population that would be observable with planned JWST surveys at 5 ? z 15. We base our study on recently developed Cosmic Archaeology Tool, which allows us to model BH seeds formation and growth while being consistent general of active galactic nuclei (AGNs) galaxies observed 4 7. find will a complementary view BHs > 5, JADES-Medium/-Deep capable detecting numerous populate faint-end distribution, COSMOS-Web sampling large enough area detect rarest brightest systems, CEERS/PRIMER bridging gap between these two regimes.
