| Description | GT- ROSAT-PSPC observations of normal edge-on spiral galaxies revealed the existence of X-ray halos in a number of cases. Questions that need to be answered are: (i) is the detected emission caused by an exceptionally high star formation rate due to nuclear activity or due to tidal interaction (ii) are X-ray halos a common phenomenon related to mass and energy transfer between the disk and halo interface due to widespread star formation activity in the disk of normal spirals? We propose to address these issues with observations of a representative sample of galaxies, for which the available X-ray data are insufficient. A large sample of objects can be used to obtain better morphological information. |

| 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. |
