Constrained by a comprehensive compilation of galaxy ($0\\leq z \\leq 10$) and SMBH datasets ($0\\leq z \\leq 6.5$), TRINITY finds: 1) The number of SMBHs with $M_\\bullet > 10^9 M_\\odot$ in the observable Universe increases by six orders of magnitude from $z\\sim10$ to $z\\sim2$, and by another factor of $\\sim 3$ from $z\\sim2$ to $z=0$; 2) The $M_\\bullet > 10^9/10^{10} M_\\odot$ SMBHs at $z\\sim 6$ live in haloes with $\\sim (2-3)/(3-5) \\times 10^{12} M_\\odot$; 3) the new JWST AGNs at $7\\lesssim z \\lesssim 11$ are broadly consistent with the median SMBH mass-galaxy mass relation for AGNs from TRINITY; 4) Seeds from runaway mergers in nuclear star clusters are viable progenitors for the SMBHs in GN-z11 ($z=10.6$) and CEERS_1019 ($z=8.7$); 5) $z=6-10$ quasar luminosity functions from wide area surveys by, e.g., Roman and Euclid, will reduce uncertainties in the $z=6-10$ SMBH mass-galaxy mass relation by up to $\\sim 0.5$ dex.", "revisions": [ { "version": "v1", "updated": "2023-09-13T18:00:00.000Z" } ], "analyses": { "keywords": [ "supermassive black holes", "median smbh mass-galaxy mass relation", "predictions", "high-redshift halo-galaxy-supermassive black hole", "nuclear star clusters" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable" } } }
