| Abstract | Recent work with XMM-Newton and Chandra has played a key role in establishing aconsensus that feedback from radio-loud AGN outbursts is an important ingredientin CDM structure formation models; however, observational constraints on theenvironmental and epoch dependence of these feedback processes are lacking. Herewe propose to measure the group/cluster environments of a carefully selectedsample of powerful (FRII) radio galaxies at z=0.5, extending to the lowest radioluminosities seen in lower redshift samples, so as to resolve the long-standingquestion of whether observed differences in FRII environments at low and highredshift are due to an environmental or an epoch dependence of radio outburstbehaviour. |

| 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. |
