| Description | The magnetic field strength in the lobes of FRII radio galaxies and quasars is a vital parameter for understanding their energetics and dynamics, since it controls the internal energy density and pressure. The only way of measuring it is by observing inverse-Compton emission from the lobes, but existing detections are marginal and do not give a consistent value for the ratio of particle to magnetic field energy density in a typical radio source. XMM.s sensitivity to extended structure makes it the instrument of choice for a systematic search for inverse-Compton emission in typical FRII radio sources. We have selected a small sample of such objects which will detect inverse-Compton emission, confirm its nature by determining its spectrum, and measure magnetic field strength to 10%. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
