|Description||Extended X-ray emission has been discovered around several distant powerful radio galaxies. The emission is most likely due to inverse Compton scattering of CMB photons by old radio synchrotron particles. The X-ray emission thus traces the total input of relativistic electrons into the surroundings of the radio galaxy, and the amount of energy injected, which will affect the gas properties of the host galaxy, group and cluster. All massive galaxies may have passed through such a phase. We propose to take a deep 60 ks observation of the exceptionally large 1 Mpc diameter, distant z=1.88 radio galaxy, 6C0905+3955, and a 20 ks observation of the 1-2 Mpc diameter z=1.08 radio galaxy 3C356. Both sources are known from our previous work to have extended X-ray emission along the radio source axis.|

|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.
