While feedback on the ISM/IGM by nucleated starbursts is well understood anddescribed, it is less obvious how distributed starformation influences theISM/IGM connection and any associated large scale flow of matter. The target ofthis proposal, NGC4700, is a unique case with two regions of very intensivestarformation symmetric to the nucleus. The filamentary structure of the diffuseionized gas and the associated radiocontinuum emission suggest a high pressureof the ISM driving a large scale outflow. X-ray observations with XMM/Newtonwill allow us to test this hypothesis and provide physical parameters importantto quantify feedback. Due to the unique morphology the target can be considereda missing link between nucleated and more distributed starbursts.

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.
