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

| 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. |
