|Title||Shocks in groups|
|Author||Dr Ginevra Trinchieri|
|Description||High resolution X-ray data of IC1262 and Stephan.s Quintet have revealed features with unusual morphologies that are interpreted in the framework of shock-heating of the intergalactic gas as a result of infall of new material, interaction and-or merging phenomena. These 2 groups have significantly different properties: IC1262 is Spiral-poor and apparently unperturbed, Stephan.s Quintet is Spiral-rich and displays strong signs of dynamical interaction. We propose XMM observations that will allow us to study the spectral properties of the shock features to better understand their nature. The comparison between them will enable us to further our understanding of environmental dependencies and-or evolutionary phases in the formation and evolution of poor groups.|

|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.
