Description | Although a good deal of indirect evidence points towards moderate or poor groups as the environment of low-luminosity (and therefore typical) FRII radio galaxies, there are almost no direct X-ray observations of the required hot, confining medium. An FRII radio source would have a dramatic effect on the gas in a group, heating and potentially expelling a significant fraction of it, with important consequences for our understanding of group evolution. In order to characterize the X-ray environments of typical FRII sources, we propose a small survey of the nearest few FRII sources of intermediate size drawn from the well-studied 3CRR catalogue. Our observations will allow us to detect, and measure the properties of, group-scale emission around our targets. |

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. |
