|Title||X-ray emission and star formation history in Spitzer-selected ETGs|
|Author||Dr Ginevra Trinchieri|
|Description||With this proposal we focus on a well selected sample of nearby ellipticals for which we reliably determine the star formation history from high S-N Spitzer and GALEX observations. We aim at determining the incidence and where possible the properties of the hot ISM in light of the detailed characteristics of their stellar population. Chosen galaxies are passively evolving systems, at most with a small episode of recent star formation. In light of current scenario we expect them to have a sizable hot ISM. We request high quality X-ray data to determine the ISM parameters, such as luminosity, spatial distribution, temperature where possible, to explore whether gas properties are homogeneous or whether even small perturbations in the SF history can alter the hot gas content.|

|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.
