Abstract

We present radio images of the edge-brightened giant radio galaxy 0319 – 454 made with the Australia Telescope at frequencies 1.5, 2.4 and 4.8 GHz. The observations show a jet and a counterjet out to exceptional distances of 380 and 590 kpc, respectively, from the radio core. 0319–454 is therefore one of only three powerful radio galaxies observed to date to have twin quasi-continuous jets. The NE lobe of the double radio structure has an extremely rare configuration of five compact hotspots that may be classified into a primary and a cluster of four secondaries. Optical imaging of the parent galaxy reveals a prominent, warped dust lane and a highly disturbed structure that is indicative of past merger activity.
