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

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
