Abstract
Neutral hydrogen is an important tracer of galactic dynamics. Hence, o bservations of the detailed structure and kinematics of HI are vital i n order to determine the relationship between AGN and their host galax y. We describe high resolution VLA emission line observations of NGC 1 068 at about 600 pc linear resolution and 5.2 km s(-1) velocity resolu tion. We present the HI morphology of this Seyfert galaxy and discuss its peculiar rotation curve and speculate how its shape might be relat ed to the Seyfert activity. Related to this, we will highlight the pro nounced HI ring within which the tightly wound CO spiral arms are foun d, and discuss the high, up to 55 km s(-1), velocity dispersions which are found there.
