Description | To use clusters as sensitive probes to study the emergence of cosmic structure and to test cosmological models we need a better knowledge of the scaling relations of cluster mass and observable properties. To improve this situation a Large Program was approved in AO3 to study 34 well selected clusters in detail. Of the first obtained observations a relatively large fraction was spoiled by high background events. We demonstrate that our observational goals cannot be reached with these compromised observations and request the reobservation of 5 of the clusters with the largest loss of exposure time. |

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. |
