Scientific paper

We present a high fidelity image of the powerful doublelobed superluminal quasar 3C179 made with MERLIN at 5 GHz. It has a knotty one-aided jet which appears to be disrupted at a 'splash' knot. Its asymmetric structure can be explained within the relativistic beaming hypothesis if the jet has slowed after the disruption. We infer that the jet is inclined at about 12-23 deg to the line sight with a speed of about 0.6-0.8 c. This is compatible with hotspot advance speed of about 0.02 c, so we need not invoke relativistic considerations to explain the hotspot asymmetry.
