Scientific paper

We have conducted (12) CO, (13) CO J=2-1, 1-0 observations of the global molecular gas reservoir in a sample of 20 Seyfert galaxies. Our purpose was to probe the excitation properties of the gas and see whether the enhanced star formation seen in the hosts of type 2 Seyferts has any discernible effect on the molecular gas. We find type 2 Seyferts to be, on average, "warmer" than type 1, however a larger sample will be needed in order to improve the statistics. On a more statistically firm ground lies our conclusion that Seyfert galaxies as a class shows a larger affinity to starburst galaxies than to non-starbursts, in terms of their molecular gas excitation.
