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.
NGC 1068是附近的2型活动星系核(AGN),这意味着它的吸积盘隐藏在大量前景消光的后面。在几个波长的观测中发现了围绕着核的各种圆盘状结构,这些结构都可能是造成AGN遮挡的假定环面的一部分。我介绍了基于近红外重力/VLTI干涉观测的结果,它提供了非常高的角分辨率,并对这个环面最内层区域的几何形状有了深入的了解。该结构的三维方向在几个方面都令人惊讶,因为它与原子核周围的其他圆盘不对齐,并且向中心源留下了清晰的视线。
