Abstract

NGC 1068 is a nearby Active Galactic Nuclei (AGN) of type 2, meaning that its accretion disk is hidden behind a large amount of foreground extinction. Observations at several wavelengths have revealed various disk-like structures around the nucleus, all possibly part of the putative torus responsible for the obscuration of the AGN. I present results based on a GRAVITY/VLTI interferometric observation in the near-infrared, which provides very high angular resolution and gives insights into the geometry of the innermost region of this torus. The 3D orientation of the structure is surprising in several aspects, as it is misaligned with other disks present around the nucleus, and leaves a clear line of sight toward the central source.
