Scientific paper

We have conducted a high resolution imaging survey of mm-wave molecular lines, i.e., CO(1-0), HCN(1-0), and HCO+(1-d$0) towards nearby Seyfert galaxies using the Nobeyama Millimeter Array and the RAINBOW interferometer. Some of Seyfert galaxies show extremely high HCN/CO and HCN/HCO+ line ratios, which are not observed in nuclear starburst galaxies. These molecular line ratios can be a new diagnostic tool to investigate the ``AGN - starburst connection'' in active galaxies.
