| Description | Giant radio galaxies, which extend to more than 1 Mpc in size, pose a difficultproblem. Their radio lobes must span regions of very different gas density andpressure, and yet they maintain relatively uniform widths over their entirestructures. This is difficult to achieve unless the lobes are propagatingthrough a medium which is more extended, and more uniform, than the gas in acluster of galaxies, but still has substantial density. We propose XMM imagingof a carefully-chosen sample of giant radio galaxies to detect X-ray emissionfrom this confining gas, and so characterise this unusual and cosmologicallyimportant medium. |

| 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. |
