Active Galactic Nucleus Structure
Recent hyper-refinement magnetohydrodynamical simulations of active galactic nuclei (AGN) have allowed for the study of physics continuously from cosmological scales down to the innermost stable circular orbit (ISCO) of a central supermassive black hole. This allows us to describe, for the first time, the steady-state structure and evolution of AGN without assuming phenomenological structure or idealized initial conditions.
In Bardati et al. (2026a), we describe one such self-consistently formed dust torus, composed of the hyper-magnetized accretion disk plus an asymmetric dusty inflowing stream that fuels accretion and predict its resulting infrared spectrum. In Bardati et al. (2026c, in prep), we also show that a combination of the disk and outflow components produces a broad line region inside the dust sublimation region that fits well with observed relations. The full simulation is described in Hopkins et al. (2025).
