Description Upcoming X-ray surveys like eROSITA, require precise calibration between X-ray
observables and mass, down to the low-mass regime to set tight constraints on
the cosmological parameters. We propose to observe 17 galaxy groups to complete
observations for a flux limited sample consisting of 69 objectss. We will use
the sample to study the scaling properties of the low-mass systems with a view
to the eROSITA survey which is expected to detect 100,000 objects, most of them
in the low mass regime. Thanks to the completeness and the size of the selected
sample we will correct for selection biases the observed scaling relations.
Furthermore, we will investigate the relative importance of non-gravitational
processes by studying their thermodynamical properties beyond R1000.

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.
