Abstract

High angular resolution mid-infrared observations with the VISIR instrument at the Very Large Telescope have allowed the distribution of dust around local active galactic nuclei (AGN) to be studied. The observational results support the unified scenario for AGN and bring constraints on the properties of its key component, a dusty torus obscuring the view onto the AGN when viewed close to the equatorial plane.
