Abstract
We present preliminary results from 1.5 '' resolution IRAM interferome ter maps of CO 2-->1 emission in the central few arcseconds of NGC 106 8. This study is unlike other studies of the CO content of this galaxy since it resolves for the first time the central dense gas concentrat ion seen previously in HCN observations. The HCN 'disk' is resolved in to two prominent peaks symmetrically located similar to 1 '' from the S1 radio peak. These peaks are likely tracing: gas located on x(2) orb its at the Inner Lindblad Resonance (ILR). The kinematic structure is also very complex with three distinct velocity components visible in t he central similar to 2 ''.
