Scientific paper

Interferometric observations of the H I and OH absorption against the nuclear radio source of NGC 3079 are presented. The absorption structure reveals three distinct absorption components associated with the nuclear disk (and torus) and the inner and outer disk structures. Weak OH emission appears in the data at about 200 km s-1 below the systemic velocity of the galaxy and coincides in velocity but not in position with the prominent H2O megamaser emission feature. The data show evidence of the nuclear jet outflow and the presence of a superbubble. The velocity information of all molecular line and other spectroscopic data provides a detailed and consistent picture of the dynamics and velocity structure of the nuclear region.
