| Abstract | The supersonic motion of radio lobes through the intergalactic medium arounda classical double radio galaxy will alter the distribution and temperature of the gas. The changed temperature and density structures are a powerful probeof the speed and momentum flux in the radio jet. High-quality X-ray images andspectra of powerful radio galaxies can measure the gas density and temperatureand hence provide fundamental data on the dynamics and energetics of radiosources which cannot be obtained using radio methods alone. Here we propose to use XMM to map the intergalactic gas near the three well-known radiogalaxies 3C 223, 284, and 98. The resulting maps of the shocks around theirradio lobes will test our understanding of the physics of radio sources. |

| 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. |
