Abstract

The "torus" is a central component of Active Galactic Nuclei models that produces the observed mid-IR emission, and obscures a large fraction of accreting black holes from direct observation. We explore whether the torus is an outflowing dusty wind driven by both magnetocentrifugal forces and radiation pressure. We have developed a model that includes these driving mechanisms and utilizes 3D Monte Carlo simulations to produce SEDs and images of the wind. We find that, in initial tests, the model is able to approximately reproduce the luminosity of the IR composite Spectral Energy Distribution when the wind has a base column of NH ∼1025 cm-2 and Moutmoumt ∼1M⊙yr-1.
