| Abstract: |
Interferometric multi-line observations of molecular emissions toward a luminous infrared galaxy NGC 6240 have been performed. HCN(1-0) and HCO+(1-0) emissions have spatially compact distributions which are peaked between the double nuclei of this galaxy. 13CO(1-0) emission is also detected, but it is much weaker than 12CO(1-0) and HCN emissions. These results suggest that the molecular gas concentrated between the double nuclei is dense and warm, and such conditions may be the product of the interaction of gas and an intense outflow from the nuclear region. |
