|Title||eeHIFLUGCS: X-Ray Masses for a Complete Sample of about 400 Galaxy Clusters|
|Author||Prof Thomas Reiprich|
|Description||Currently, the largest complete local X-ray cluster sample with full high quality X-ray coverage is HIFLUGCS. Its selection is based on the ROSAT All-Sky Survey and complete X-ray follow-up has been performed with Chandra and XMM-Newton, resulting in numerous applications in cluster physics and cosmology. The combination of high completeness, large sample size, and high quality follow-up has been crucial for this wide applicability. Here, we propose a sixfold increase in sample size with a new complete high quality sample of virgul400 clusters, eeHIFLUGCS. We demonstrate that this sample constitutes the ultimate step before eROSITA and that this significantly increased statistics will enable substantial (factor virgul3) improvements in precision as well as qualitatively new tests.|

|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.
