3C254: MERLIN observations of a highly asymmetric quasar
  Multifrequency, high-resolution radio observations of the quasar 3C254 using MERLIN are presented. The quasar has a highly asymmetric radio structure, with the eastern component of the double-lobed structure being much closer to the nucleus and significantly less polarized than the western one. However, the two lobes are more symmetric in their total flux densities. The observations show the detailed structure of the hotspots which are very different on opposite sides of the radio core, reveal no radio jet and suggest that the oppositely-directed jets may be intrinsically asymmetric.
