|Title||Fe K-alpha Emission in the Bright Elliptical Galaxy NGC 1399|
|Author||Prof David Buote|
|Description||A precise measurement of the Fe K-alpha line emission in an elliptical galaxy will be possible for the first time with the EPIC pn on XMM. The equivalent width of the Fe K complex in the bright elliptical NGC 1399 will distinguish between rival spectral models for the temperature structure of the hot ISM inferred from previous analyses of the Fe L complex which predict very different Fe abundances in each case. The unprecedented accuracy of the Fe abundance achieved with these data will provide the strongest constraint to date on the star formation history of an elliptical galaxy.|

|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.
