Scientific paper

All 506 galaxies in Markarian's first five lists were surveyed at 6-cm wavelength with a 3-sigma detection limit of about 30 mJy. Twenty-eight galaxies were detected. The Markarian galaxies with Seyfert characteristics have higher radio luminosities. Among these, radio emission is predominantly detected from galaxies of color type II and from those having the more diffuse d nuclei. Among the non-Seyfert Markarian galaxies, those without any spectral lines are more often detected, and these tend to have the more condensed s-type nuclei. There is a tendency for galaxies which are double, or which have ejections, tails, or some form of optical peculiarity, to also have detectable radio emission.
