Description
First results from the AGN-Heidelberg program aimed at resolving the
central pc region of the closest Active Galactic Nuclei in the IR are
presented. The core region of prototype active nuclei are clearly
unveiled at IR waves and at distances from the nucleus - few pc- where
circumnuclear starforming regions appear not to be present. Within that
perspective, classical active nuclei as Circinus and NGC 1097, reveal
with unprecedented detail clear channels of material being driven to the
core whereas others as Centaurus A and NGC 1566, show a `clean' core
environment. At the very center, a central compact region of about 2 pc
scale is resolved in Circinus but not in the other cases challenging
thus the universal presence of the putative obscuring torus.
