|Title||The richest superclusters in SDSS-redMaPPer|
|Author||Dr Ming Sun|
|Description||Superclusters, as the largest cosmic structures, are important to study the evolution of galaxy clusters and groups, cosmic baryons (e.g., the warm hot intergalactic medium) and galaxy evolution. There have been few studies of superclusters in X-rays, while the X-ray data remain as the key to study the bulk of baryons in superclusters. We select the two richest superclusters from the SDSS-redMaPPer cluster catalog and propose XMM observations to map both of them. They are extreme mass concentrations with the total mass at least several times higher than well-known superclusters like A901-2. The XMM data will be used to map the mass distribution (along with our weak-lensing work), study merger dynamics and examine the cosmic filaments, and provide us important insights on superclusters.|

|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.
