Description 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 a 0.1-2.4 keV luminosity limit of 10E35erg-s - a factor of 10 deeper than earlier ROSAT observations. EPIC spectra and hardness ratios are used to separate between different source classes. We search for short term time variability, pulsations of the order of 1 to few 100 s and long term variability, i.e. binary light curves, transients. We spectrally characterize the diffuse component that is correlated with the inner spiral arms. Here, we re-propose observations that were dominated by high EPIC background or used EPIC with the thick filter.

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.
