| Abstract | Clusters of galaxies are great objects to study cosmology and astrophysics.There are many cluster samples selected from ICM-based observations (X-ray andSZ). However, the ICM-based selections are also ICM-biased, e.g. X-rayselections are biased to cool core clusters. The results from these ICM-biasedsample can affect the constraints on the cluster cosmology and baryon physics.We select an optically rich cluster sample from the redMaPPer catalog. We findmost of them that uncovered by modern X-ray telescope are X-ray faint clusters.We request XMM observations for them in order to have a complete and unbiasedview of ICM properties. The results will provide helpful guidance for futuresurveys. |

| 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. |
