Abstract | Powerful radio galaxies at high redshift tag clusters which have developedsignificant atmospheres but otherwise should be typical of their redshifts.XMMs large throughput provides an unprecedented opportunity for spectralmeasurements of such clusters. We propose to observe 4 high-redshiftradio galaxies selected in an unbiased way from the complete 3CRR radiocatalogue. The X-ray luminosities and temperatures, together with th^el of sub-clustering in the fields, will be used to probe cosmologicalmodels. The results, in conjunction with our SIRTF study of star formationin the galaxies and total mass estimates of the clusters, will determinethe extent to which these systems are dynamically young. |

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. |
