It is proposed to observe the X-ray emission of the edge-on galaxy NGC5775,known to possess an extended diffuse ionized gas halo and a radio continuum halo, in order to search for an associated hot phase of the ISM in the halo.Since models of the ISM describe the presence of halo gas in the context of alarge scale transport of matter from the disk into the halo, which is driven bythe star formation in the underlying disk, the presence of DIG in the halo is avery good indicator for such a process in action. The spatial distribution andspectral information of the halo gas obtained with XMM will allow us to answersome important questions with regard to the transport mechanisms and energeticsof the disk-halo connection.

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.
