A 45 deg2 radio continuum imaging campaign of the nearest radio galaxy, Centaurus A, is reported. Using the Australia Telescope Compact Array and the Parkes 64m radio telescope at 1.4 GHz, the spatial resolution of the resultant image is ~600 pc, resolving the ~500 kpc giant radio lobes with approximately five times better physical resolution compared to any previous image, and making this the most detailed radio continuum image of any radio galaxy to date. In this paper, we present these new data and discuss briefly some of the most interesting morphological features that we have discovered in the images... abstract truncated.

Comments
ApJ in press. This version (now accepted in ApJ) now replaces the earlier submission. Changes made between two versions include updated explanation of how we made Figure 2, the inclusion of Figures 7a and 7b showing cuts across the lobes to highlight sharp and not-sharp lobe boundaries
