The dusty torus in active galactic nuclei (AGN) is supposed to play a key role in regulating AGN activity and evolution in providing the connection between the host galaxy and the accretion disk around the central supermassive black hole. Despite its importance for AGN activity, little is know about the structure, dynamics, and physical processes in the torus due to the small angular scales involved (smaller than sub-arcsecond). The proposed project aims at a better physical understanding of the dust torus by combining (1) high-spatial resolution infrared (IR) observations - adaptive-optics-assisted and interferometry - which spatially resolve the torus emission, (2) detailed 3-D radiative transfer simulations, and (3) theoretical work on dust physics in the AGN environment.Here, I am applying for non-cash assistance (Sachbeihilfe) to fund project-related costs that are not covered elsewhere. In particular, this concerns publication costs, and travel costs for observation runs and international conferences.
