Description GT - X-ray spectra of Seyfert II galaxies exhibit discrete spectral features in the soft X-ray band. The line formation mechanisms are not well understood and detailed spectroscopy will provide a wealth of information about the structure of the circumnuclear regions. Mkn 3 is one of the brightest Seyfert II galaxies in soft X-rays and we propose to obtain high resolution X-ray spectra of the emission-line regions in Mkn 3. We will determine the emission mechanisms of the emission-line regions and constrain the ionization structure of the active nucleus.

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.
