GT- Starburst galaxies are the most suitable objects for studies of the hotphase of the ISM in spirals. They have the highest star formation (SF) rates andthus the hot ISM with the largest volume filling factors (about 0.5). As part oftheir superwinds, starbursts also have hot gaseous halos. These can be studiedin order to determine which processes heat the gas and also to put constraintson the chemical composition of the gas. New models of the ISM, like e.g. thechimney or the galactic fountain model consider disk-halo interactions as anatural extension of a dynamical SF-heated disk ISM. The new observations willplace tighter constraints on these models than currently available and help usdetermine the bst description of galaxies, depending on their SF rate.

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.
