Abstract

A high-resolution image of the strong extragalactic source 1343–601 has been made with the Molonglo Observatory Synthesis Telescope (MOST) at 843 MHz. The source is identified with a 10 mag galaxy (Mv = −24) which is heavily obscured through our Galaxy. A recent redshift (z = 0.01215) gives a distance of 73 Mpc and a corresponding radio luminosity of log P843 = 24.9.

The MOST image shows a core linked by a double jet to asymmetric lobes which are surrounded by a confined balloon (400 × 200 kpc2) of low-brightness plasma. This has a complex network of ridges or flows which lead out into the wider cluster medium. If similar balloons exist around other double sources, they could provide the depolarising medium required by the Laing-Garrington effect.

Separate observations show the core is compact with strong X-ray emission.
