CO observations of ultrasoft active galactic nuclei.

We have observed a sample of four ultrasoft X-ray-emitting AGN in the emission line of CO (J= 1-0) using the NRAO 12-m telescope. The sample includes AGN that have a strong component of hard X-ray emission and AGN that lack a detectable hard X-ray component. We have detected CO emission from one AGN (E 1227.0+1403, z = 0.10) and set upper limits on the CO emission from the remainder. This detection is at a fairly substantial redshift for AGN CO detections. Based on further X-ray ad optical data, we propose that the CO-emitting gas in this galaxy is in a toroidal configuration, surrounding a coaligned accretion disc at the centre of the AGN.
