|Title||Getting ready for eROSITA: characterizing a well defined SZ sample of clusters|
|Author||Dr Lorenzo Lovisari|
|Description||Since SZ samples are thought to be representative of the true cluster population one can use them to estimate, and eventually correct, the biases in the scaling relations derived with X-ray selected samples. We propose to observe 18 galaxy clusters with a total exposure time of 226ks to complete the observations of the Planck Cosmological Reference Sample consisting of 189 clusters. The oservations will allow us to completely characterize the sample in terms of dynamical state and therefore enable detailed studies of key cluster scaling relations. With these results in hand we will be able to investigate the physics behind the differences observed in the properties of X-ray and SZ selected samples and determine proper bias corrections to be used in the near future with eROSITA.|

|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.
