Abstract
We propose to identify the location of the MIR emission from a pilot
sample of unobscured AGN. We will distinguish the dusty material
associated with the optically and geometrically thick torus of the
unified AGN scheme, which arises on small (<10pc) scales, from the
dust associated with the spectrally narrow optical emission lines,
which extends over larger (100pc) scales. Indirect evidence for
large-scale MIR emission arises in distant quasars, but
ground-based observations of nearby Seyfert galaxies offer the
best possibility of resolving the emission directly. Isolating the
small-scale emission, we will test novel models of clumpy tori to
determine the distribution of dusty material in detail.
