Title The confinement of powerful extragalactic radio sources

Description We propose deep observations of the nearest classical double (FRII) radio galaxies, to search for the medium which provides ram-pressure confinement for the radio lobes. This will allow us to eliminate fundamental uncertainties in the energetics and timescales of the jets and AGN. The EPIC spectra will show whether the emission is dominated by unshocked or shocked gas (the ratio will depend on the shock strength). To minimise confusion from AGN emission, our targets are narrow-line objects with weak nuclear X-ray emission. On the well supported orientation unified scheme, the lobes in NLRG are close to the sky plane, so projection effects are unimportant. We should also detect inverse Compton from radio lobes, unless field strengths are well above equipartition.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
