1987ApJ...313..651E Broad-band properties of the CfA Seyfert galaxies. I - Radio properties R. A. Edelson Abstract. Quasi-simultaneous high-sensitivity observations of a complete, unbiased sample of 42 bright, spectroscopically selected Seyfert galaxies have been made at 1.5, 6, and 20 cm. All of the objects observed were detected above 0.3 mJy at 6 cm. It appears that about 25 percent of the Seyfert 1 galaxies have highly curved spectra which flatten out toward higher frequencies. This may be due to emission from a compact core or from the low-frequency side of the infrared power law. There is evidence for extended emission, probably from the disk of the underlying galaxy, in about half of the objects studied. There is no significant difference in the mean 6 cm radio luminosity of types 1 and 2 Seyfert galalxies in this well-defined sample. The radio luminosity of Seyfert galaxies is well correlated with optical luminosity but not with the presence of nearby companion galaxies.
