| Abstract: |
Since many years, VLBI technics allow to explore AGN structures at the milliarcsecond scale in the radio range. This provided a wealth of information mainly on the jet physics, and on some circumnuclear disks. The present decade is now allowing a zooming towards AGNs in the infrared and optical ranges. The advent of large interferometers (VLTI, KIIA) at these wavelengths will soon open a new window on compact cores, accretion and ejection features, dust content, stellar environnement, and interconnection between these constituents. In the northern hemisphere, the OHANA project of interferometry between large telescopes of the Mauna Kea will combine the highest sensibility with the highest angular resolution (o.2 milliarcsecond in the J band). We will illustrate how confrontation of simple models of nuclear jets, broad line regions, circumnuclear disks and starbursts to expected interferometric parameters can constrain AGN physics. |
