|Title||The X-ray halo of NGC 4634|
|Author||Prof Ralf-J rgen Dettmar|
|Description||The metal content of the interstellar and intergalactic medium is one of the most sensitive and significant imprints of the star formation history over cosmological time-scales. In current models feed-back mechanisms are crucial to explain the observed properties of galaxies. In a survey of X-ray properties of edge-on disk galaxies we have identified NGC 4634 as a target best suited to study the properties of an outflow governed by the distributed star formation. We propose to obtain X-ray spectra with significantly higher S-N to better constrain the metal content of the gaseous halo. We want to extract spatially resolved spectra which will allow us to discuss the enrichment and mixing processes and compare it with wind models.|

|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.
