Abstract The metal content of the interstellar and intergalactic medium is one of themost sensitive and significant imprints of the star formation history overcosmological time-scales. In current models feed-back mechanisms are crucial toexplain the observed properties of galaxies. In a survey of X-ray properties ofedge-on disk galaxies we have identified NGC 4634 as a target best suited tostudy the properties of an outflow governed by the distributed star formation.We propose to obtain X-ray spectra with significantly higher S/N to betterconstrain the metal content of the gaseous halo. We want to extract spatiallyresolved spectra which will allow us to discuss the enrichment and mixingprocesses and compare it with wind models.

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.
