Abstract: |
We present the results of CO and HCN observations of the early-type galaxies NGC 404, NGC 3593, and NGC 4293, using the Nobeyama 45 m telescope. We detected HCN emission from NGC 3593 and NGC 4293. The HCN emission profiles show large differences from the profiles of CO emission. The HCN emission is weak at the systemic velocity of these galaxies, while the CO emission has a peak at this velocity. The HCN/CO intensity ratios in these galaxies are comparable to those of late-type spirals. We present also the preliminary results of high-resolution observations of NGC 4293 with the Nobeyama Millimeter Array (NMA). |
