We propose to use XMM to measure the spatial distribution and temperature in the hot phase of the ISM in NGC 625, a nearby,low mass dwarf irregular galaxy with a central starburst. Recent optical (ground-based and HST) and x-ray (ROSAT) observations haverevealed the starburst in this very nearby (D \le 4 Mpc) memberof the Sculptor Group. Using XMM we will map the hot galactic outflow and determine its physicalparameters. Together with our HI and optical data we will perform a detailedobservational case study on NGC 625 in order to test theoretical predictions ofdwarf galaxy evolution, in particular, their ability to enrich the IGM and ICM.

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.
