Abstract With this proposal we focus on a well selected sample of nearby ellipticals forwhich we reliably determine the star formation history from high S/N Spitzer andGALEX observations. We aim at determining the incidence and where possible theproperties of the hot ISM in light of the detailed characteristics of theirstellar population. Chosen galaxies are passively evolving systems, at most witha small episode of recent star formation. In light of current scenario we expectthem to have a sizable hot ISM. We request high quality X-ray data to determinethe ISM parameters, such as luminosity, spatial distribution, temperature wherepossible, to explore whether gas properties are homogeneous or whether evensmall perturbations in the SF history can alter the hot gas content.

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.
