Description Recent work with XMM-Newton and Chandra has played a key role in establishing a
consensus that feedback from radio-loud AGN outbursts is an important ingredient
in CDM structure formation models; however, observational constraints on the
environmental and epoch dependence of these feedback processes are lacking. Here
we propose to measure the group/cluster environments of a carefully selected
sample of powerful (FRII) radio galaxies at z=0.5, extending to the lowest radio
luminosities seen in lower redshift samples, so as to resolve the long-standing
question of whether observed differences in FRII environments at low and high
redshift are due to an environmental or an epoch dependence of radio outburst

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.
