| Abstract | We propose to perform snapshot observations of a population of clusters whichemerged in the Second Planck Catalogue of SZ sources as being under luminous inX-rays with respect to the prediction based on their measured SZ flux. Thisprogram will allow us to confirm or challenge the detection of these objects byfirmly assessing their flux, to measure their gas content and to map the gasdistribution, allowing us to discriminate between different scenarios for theirorigin. The detection of this population of objects has important implicationsfor understanding selection effects in SZ and X-ray surveys, for thereconstruction of the mass function of galaxy clusters and for the calibrationof scaling relations. |

| 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. |
