Dwarf galaxies are the most susceptible to energetic feedback from massivestars, and are the most plausible sources of the early heating and enrichment ofthe IGM by galactic winds. X-ray data are vital to study this process, as theyare the most direct probe of the hot gas that contains the majority of theoutflowing energy and metals. NGC 1705 is the prototypical example of astarburst-blown bubble blowing-out of the ISM. We propose to obtain XMM-Newtonimaging spectroscopy of this galaxy. In conjunction with our existing FUSE andHST far-UV spectroscopy, these data will directly test the standard paradigm forthe dynamical evolution of superbubbles and winds in dwarf galaxies andelucidate the physical origin and long-term fate of the hot X-ray-emitting gas.

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.
