Abstract

  Supermassive black holes (SMBHs) exist in many galaxies. Their growth is accompanied by strong energy output, which is capable of regulating host galaxy evolution. Understanding SMBH growth is thus critical for studying galaxy formation and evolution. However, it has been difficult to quantify SMBH growth in different galaxies and cosmic epochs. In this talk, I will present Trinity, an empirical technique to determine the typical SMBH mass and growth rate in different galaxies and dark matter halos from z=0-10. I will discuss how the galaxy—SMBH connection from Trinity will help observational astronomers extract more information from data, as well as theoretical astronomers create better simulations of galaxy evolution. In addition, I will give an overview of the Trinity predictions that match latest JWST data, as well as those that do not match observations. Finally, I will talk about how observations with next-generation telescopes will enable a better understanding of the galaxy—SMBH connection, and how Trinity will be helpful for quantifying the constraining power of future observations.
