1974ApJ...187...11D RADIO OBSERVATIONS OF TWO CLUSTERS OF GALAXIES F.F. Donivan, Jr. Department of Physical Sciences, University of Florida, Gainesville and T.D. Carr and G.C. Omer, Jr. Department of Physics and Astronomy, University of Florida, Gainesville Received 1973 May 14 Abstract Maps including the Coma and Hercules clusters of galaxies were made at 195, 318 and 611 MHz, and were compared with optical counts of galaxies in the clusters. An extended region of radio emission approximately 20 arcmin in diameter was observed at the center of the Coma cluster. A distributed source region was also observed which appears to include the Hercules cluster, although the possibility that it is just an irregularity in the Galactic foreground radiation cannot be completely ruled out.
