|Title||X-ray spectroscopy of the LINER NGC7213|
|Author||Dr Bert Brinkman|
|Description||GT - Detailed X-ray spectral information will help to distinguish between the emission mechanisms present in this bright LINER. If it contains a .dwarf. AGN, it should show a compact, variable source whose X-ray emission has a non-thermal power-law form. It may also show strong Fe K-alpha line emission produced by fluorescence in cold matter. On the other hand, nuclear starbursts are frequently extended over kpc scales and are expected to show thermal spectra characterised by coronal X-ray emission lines.|

|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.
