摘要: This Letter presents new Near-Infrared Camera and Multi-Object Spectrometer data on the location of nucleus morphology hydrogen [Si VI] emission in NGC 1068. The peak at 2.2 μm is a strong point source that marks nucleus. line region consists two main components, diffuse coronal to north-northeast bright spot 16 from along direction radio jet. A similar but less intense also occurs Paschen-α Wide Field Planetary 2 Hα images. accurate determination nuclear position its relation emission-line produces clearer picture nature interaction between jet surroundings.
