1995A&A...293...56N The radio-FIR correlation of galaxies in the Virgo Cluster S. Niklas, U. Kiein, and R. Wielebinski Max-Planck-Institut fur Radioastronomie, Auf dem Hugel 69, D-53 121 Bonn, Germany Radioastronomisches Institut, Universitat Bonn, Auf dem Hugel 71, D-53121 Bonn, Germany Received 24 March 1994/Accepted 3 May 1994 Abstract. The radio emission at {lambda}{lambda}6.3 cm and 2.8 cm of a sample of Virgo galaxies was measured and compared with the flux density expected from the radio-FIR correlation. We find that most of the galaxies in the Virgo Cluster behave like normal field galaxies. Only a few early type spirals with strong central sources as well as very disturbed galaxies show an excess of radio emission. Galaxies which show a high radio excess are located in the inner part of the cluster. This is probably related to the influence of the cluster environment. For a number of Virgo galaxies integrated spectra are obtained and the spectral indices are calculated. The spectra do not appear to be affected by the location of the galaxies within the cluster.
