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.
