We present Trinity, an empirical model that infers the statistical connection between dark matter halos, galaxies, and supermassive black holes (SMBHs) from z=0-10. Required to fit to a comprehensive galaxy and active galactic nuclei (AGN) dataset, Trinity constrains: (1) Typical host halo/galaxy masses for any SMBH population given their redshift, mass and/or Eddington ratio; (2) Average accretion and merger histories of SMBHs in different halos/galaxies (3) AGN duty cycles as a function of halo/galaxy mass and redshift. These predictions will test the potential processes feeding gas to SMBHs, as well as the feedback mechanisms coupling SMBHs to their host halos and galaxies. The code and mock light cone data will be publicly available for the community to maximize the outcome of future observations by, e.g., JWST, LSST, and LISA. In the future we will incorporate Trinity with the UniverseMachine to study environmental effects on the halo—galaxy—SMBH connection.
