ABSTRACT | |
Our previous X-ray inverse-Compton and environmental studies of radio galaxies have demonstrated that their composition depends on morphology: edge-brightened, luminous (FRII) radio galaxies are leptonic, while centre-brightened, low luminosity (FRI) radio galaxies are baryonic. Radio morphology is therefore crucial for the inference of jet power and feedback from AGN survey populations. But the traditional FR dichotomy is challenged by our recent discovery of a large population of low luminosity edge-brightened (FRII) sources in the LOFAR Two-Metre Sky Survey (LoTSS). Here we propose to measure lobe inverse-Compton and environmental emission from this new AGN class to determine their particle content and hence enable their environmental impact to be incorporated into feedback models. |
