Abstract In a GT raster observation of the bright local group spiral galaxy M33 we study the population of X-ray sources (SNRs, XRBs, supershells) down to a0.1-2.4 keV luminosity limit of 10E35erg/s - a factor of 10 deeper thanearlier ROSAT observations. EPIC spectra and hardness ratios are used toseparate between different source classes. We search for short term timevariability, pulsations of the order of 1 to few 100 s and long termvariability, i.e. binary light curves, transients. We spectrallycharacterize the diffuse component that is correlated with the inner spiralarms. Here, we re-propose observations that were dominated by high EPICbackground or used EPIC with the thick filter.

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.
