| Abstract | We propose XMM observations of four relic radio galaxies, withthe goal of detecting inverse Compton scattered microwavebackground radiation. Detection of this emission would yieldboth a measurement of the relativistic electron density andthe magnetic field, directly testing assumptions of equipartition,and providing a unique probe of conditions in the surrounding IGM.XMMs high sensitivity and broad bandpass are ideally suitedto these observations. Non-detection by XMM would imply extremedepartures of the particles and fields from equipartition, itselfa surprising and important result. |

| 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. |
