Observational Predictions from a Cosmological Simulation of a Quasar Starburst Galaxy Zoomed to the Supermassive Black Hole's Innermost Stable Orbit

Despite being vital to many observational goals and high-redshift measurements, the structure of highly accreting active galactic nuclei (AGN) and their connection to larger galactic environments remain elusive. Recently, it has become possible to self-consistently zoom-in from cosmological scales down to the innermost stable orbit of accreting supermassive black holes. In this talk, we present the first observational predictions from a self-consistent cosmological simulation of a super-Eddington accreting AGN. In particular, we discuss (1) the dust torus structure and inferred infrared (IR) spectral emission, (2) the total inferred rest-frame optical/UV to IR emission including the galactic starburst contribution, and (3) the broad line region structure, emission properties, and possible variability signatures. Our system undergoes an IR bright phase early in its evolution, due to both starburst and the AGN emission, causing the system to appear similar to a slightly lower luminosity hot dust obscured galaxy overall. However, the system varies significantly enough across sightlines to change the IR spectral slope and thus possibly the inferred galaxy classification.
