Abstract	If radio galaxies have a finite lifetime, then there should exist dying or relicexamples i.e. radio galaxies whose central engines have ceased to be active butwhose extended lobes have not yet faded from view. But only a very few are knownat radio wavelengths: they are so rare because the relic stage is veryshort-lived for a radio galaxy whose lobes are no longer continuously injectedwith freshly accelerated particles from the hotspots. Though relic radiogalaxies are very rare, they represent an unexplored phase in the life-cycle ofradio galaxies: as radio galaxies die, their relativistic particles lose energybut dramatically increase the population of Lorentz factor 1000 particles which,importantly, inverse-Compton upscatter CMB photons to the X-ray band.

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.
