Our previous X-ray inverse-Compton and environmental studies of radio galaxies have demonstrated that their composition depends on morphologydoublePoint edge-brightened comma luminous openParFRIIclosePar radio galaxies are leptonic comma while centre-brightened comma low luminosity openParFRIclosePar 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 openParFRIIclosePar sources in the LOFAR Two-Metre Sky Survey openParLoTSSclosePar. 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.
