| Description | We have been awarded a Large Program in AO4 to study the evolution of cluster structural and scaling properties, using a large sample of distant clusters (zvirgul 0.5) covering a wide dynamic range in mass (2.5 < kT < 12 keV). Our aim is to provide new insight into the physics of structure formation, both for the dark matter and the baryonic components. We propose to re-observe 2 targets, the observations of which are dramatically affected by flares. To complete the kT > 5 keV range coverage of our sample, we also propose to observe 3 clusters, for which no time was allocated in AO4. |

| 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. |
