The radio spectra of Markarian galaxies

Abstract

Radio flux densities between 2.7 and 15.5 GHz are given for 16 Markarian galaxies. Spectra for these objects are obtained from these and previously published data. The Seyfert-type galaxies show power-law spectra with an average index of -0.82, except for MRK 348, which is an active galaxy with a complex spectrum. The Markarian galaxies with featureless optical spectra have rather flat radio spectra, similar to the BL Lacertae-type objects.
