| Description | GT- X-ray shadow experiments are important, because they help us to determine the distribution of the X-ray plasma in our Galaxy. Recent results (Kerp et al. 1997, Pietz et al. 1997) indicate that our Galaxy has an extended X-ray halo. This halo plasma accounts for the 1/4 keV as well as for the 3/4 keV background radiation. The aim of this proposal is to improve our view of the X-ray backgr. Based on our experience with the ROSAT PSPC, we will use EPIC imaging spectra to derive the 3-D composition of X-ray mietting and absorbing matter distributed along the line of sight by analysing X-ray colours and to determine whether the Galactic halo plasma or a steepening of the extragalactic power law causes the observed increase in the background intensity towards lower photon energies. |

| 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. |
