中性氢是星系动力学的重要示踪剂。因此，详细的结构和运动学的HI的观测是至关重要的，以确定活动星系核和他们的宿主galaxy.We描述的高分辨率VLA发射线观测NGC 1068在约600 pc的线性分辨率和5.2 km s-1的速度分辨率。我们给出了这个Seyfert星系的HI形态，讨论了它独特的自转曲线，并推测了它的形状与Seyfert活动的关系。与此相关的，我们将突出明显的HI环内的紧密缠绕的CO旋臂被发现，并讨论了高，高达55公里s-1，速度分散体被发现有。
Neutral hydrogen is an important tracer of galactic dynamics. Hence, observations of the detailed structure and kinematics of HI are vital in order to determine the relationship between AGN and their host galaxy.We describe high resolution VLA emission line observations of NGC 1068 at about 600 pc linear resolution and 5.2 km s-1 velocity resolution. We present the HI morphology of this Seyfert galaxy and discuss its peculiar rotation curve and speculate how its shape might be related to the Seyfert activity. Related to this, we will highlight the pronounced HI ring within which the tightly wound CO spiral arms are found, and discuss the high, up to 55 km s-1, velocity dispersions which are found there.
