The radio brightness distribution of eight Markarian galaxies.
Abstract
Results of radio aperture-synthesis observations at 2.7 and 8.1 GHz are given for eight Markarian galaxies. Five of these galaxies are Seyfert-type objects (MRK 1, 3, 231, 273, and 348) and one is a BL Lacertae object (MRK 501); these exhibit only an unresolved radio nucleus. Two other galaxies show an extended source (MRK 297) and a double source inside the optical image (MRK 171). This double source coincides with optically bright regions that are off-center with respect to the general outline of the galaxy.
