cds-question@unistra.frgalaxy-clustersradio-galaxiesradio-continuum-emissionNew radio continuum observations of galaxies in the Virgo cluster region at 4.85, 8.6, and 10.55GHz are presented. These observations are combined with existing measurements at 1.4 and 0.6GHz. The sample includes 81 galaxies where spectra with more than two frequencies could be derived. Galaxies that show a radio-FIR excess exhibit central activity (HII, LINER,AGN). The four Virgo galaxies with the highest absolute radio excess are found within 2 degrees of the center of the cluster. Galaxies showing flat radio spectra also host active centers. There is no clear trend between the spectral index and the galaxy's distance to the cluster center.2004A&A...418....1Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/418/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/90/1681 : The Virgo Cluster Catalog (VCC) (Binggeli+, 1985)J/A+AS/127/367 : Virgo Photometry Catalogue (VPC) (Young+ 1998)J/A+A/343/86 : Virgo cluster radio luminosity function.
