| Abstract: | VLA observations at 6 cm have been made of 16 distant luminous 3C sources that appeared to be unresolved or slightly resolved
in Cambridge maps but which were known from VLBI observations to contain significant fine structure on the scale of about
1 kpc in their lobes. The general morphology of these sources is very similar to that of their nearby powerful counterparts;
most of the lobes contain low brightness tails which are often directed from the hot spots towards the associated optical
object. The hot spots are generally unresolved by the VLA observations; in 3C 254, 3C 268.4 and 3C 352, one of the lobes contains
two hot spots. |
