| Abstract | The largest fraction of matter content in the Universe is attributed to galaxygroups, therefore they play a key role in astrophysics and cosmology. UpcomingX-ray surveys like eROSITA, require precise calibration between X-rayobservables and mass, down to the low mass regime to set tight constraints onthe fundamental cosmological parameters. We propose to observe 14 galaxy groupswith a total exposure time of 137 ks to complete observations for a flux limitedsample consisting of 69 objects. The requested data will allow to preciselycorrect for selection effects the scaling relations, with an improvement on thecorrected scaling relations by a factor of 2 with respect to what can be donewith the current data. |

| 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. |
