Description
The broadband emission from the lobes of radio galaxy Centaurus A (Cen A) has been widely considered to be produced via a simple leptonic model, i.e., synchrotron and inverse-Compton scattering. More recently, gamma-ray data from the Fermi Large Area Telescope (LAT) has hinted at a spatial mismatch with the radio and microwave images of the Cen A lobes, challenging the simple leptonic scenario. We present a morphological analysis of the Cen A lobes, confirming this phenomenon and providing a full 9 year Pass 8 LAT gamma-ray image of the lobes. In light of this analysis, we offer alternative production scenarios which may account for the observed mismatch.
