Scientific paper

Perseus A, 4C 12.50, and Cygnus A have been observed in the CO(J = 1 to 0) line. In Perseus, an estimate of 3.2 x 10 to the 9th solar masses is found for the molecular gas in the giant galaxy in the cluster center. An upper limit of M(H2) = 9 x 10 to the 9th solar masses is obtained for the galaxy in the center of Cygnus A. The results suggest that large amounts of molecular gas, and thus high rates of star formation, are involved in the genesis of the central engines that power extragalactic radio sources.
