| Abstract | We propose deep observations of the nearest classical double (FRII) radiogalaxies, to search for the medium which provides ram-pressure confinement forthe radio lobes. This will allow us to eliminate fundamental uncertainties inthe energetics and timescales of the jets and AGN. The EPIC spectra will showwhether the emission is dominated by unshocked or shocked gas (the ratio willdepend on the shock strength). To minimise confusion from AGN emission, ourtargets are narrow-line objects with weak nuclear X-ray emission. On the wellsupported orientation unified scheme, the lobes in NLRG are close to the skyplane, so projection effects are unimportant. We should also detect inverseCompton from radio lobes, unless field strengths are well above equipartition. |

| 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. |
