Abstract
We present new radio and optical images of the nearest radio galaxy Centaurus A and its host galaxy NGC 5128.We focus our investigation on the northern transition region, where energy is transported from the ~5 kpc (~5 arcmin) scales of the northern inner lobe (NIL) to the ~30 kpc (~30 arcmin) scales of the northern middle lobe (NML). Our Murchison Widefield Array observations at 154 MHz and our Parkes radio telescope observations at 2.3 GHz show diffuse radio emission connecting the NIL to the NML, in agreement with previous Australia Telescope Compact Array observations at 1.4 GHz. Comparison of these radio data with our wide-field optical emission-line images show the relationship between..
