We propose relatively deep XMM observations of 3 high redshiftradio--galaxies in order to study the origin of their X--ray emission.In particular we want to test if a hot thermal gas possibly associatedwith high redshift cluster is present or if a Invers Compton emissionof the nuclear photons off the relativistic electrons in the radio lobesis responsible of the weak X--ray fluxes observed by ROSAT.

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.
