Abstract

We have investigated the correlation between previously published X-ray (0.5-4.5 keV) and carbon monoxide (CO) luminosity data of 13 Seyfert 1 galaxies and five quasars and found that there may be a significant correlation between these quantities. The correlation between CO and far-infrared luminosities of these objects is found to be similar to those of the nearby spiral and starburst galaxies. These results may indicate that the more powerful monsters live in the more actively star-forming host galaxies. There are two distinct exceptions here, however; Mrk 231, whose X-ray luminosity is smaller by two orders of magnitude than the value expected from the correlation, and Mrk 376, whose X-ray luminosity is too high by at least an order of magnitude compared to the correlation. Confirmation of this potentially important result with a larger and much more well-defined sample is urgently needed.
