| Abstract | We propose the observation of the elliptical galaxy NGC 3216 which has been identified in the ROSAT Bright Survey (RBS) as a strong X-ray source. Its X-raybrightness which is close to a quasar luminosity and the pure galaxy spectrum in the optical band let us assume that NGC 3216 belongs to the class of type-2 AGN which plays a major role in the population synthesis models. In this case we would have a nearby object excellent for studies of this AGN population.An interesting alternative explanation is that ROSAT has seen one of the rare X-ray transient sources in which a star was disrupted by tidal forces of a massive black hole. The proposed observation will give us a precise position ofthe X-ray source and will unveil its nature. |

| 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. |
