| Abstract | GT- XMM observations of M83 will cover the whole optical extent of the galaxy and will enable a study of the different components of the hot interstellar medium. Possible components of nuclear activity will be visible in the XMM band, even if the AGN is surrounded by obscuring torii of molecular material. The face-on orientation minimizes absorption of point sources and allows us anunbiased search for sources in the bulge and disk as well as a study ofthe their spatial distribution. The spectral investigations with XMM willtell us about the nature of the sources (SNRs or binaries). The origin offainter sources may be disentangled with help of their X-ray colours(hardness ratios) and long term time variability. |

| 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. |
