Zhang: JWST has found many more supermassive black holes (SMBHs) at z>4 than we expected. In addition, some of these SMBHs show spectacular properties, such as their masses given their redshifts and host galaxy masses. Nonetheless, it is difficult to reconstruct their evolution histories and connect these high-z SMBHs with their low redshift analogs. In this talk, I will present TRINITY, a new data-driven model to reconstruct SMBH growth histories in different galaxies from z=0-10. Based on my predicted galaxy—SMBH connection, I will show when JWST AGNs become overmassive. In addition, I will show how TRINITY connects different observed SMBH populations at different redshifts and enable better understanding of SMBH growth across cosmic time.
