We propose a joint, 100 ks Chandra and 30 ks XMM-Newton study of thelow-metallicity galaxy NGC3109. By combining unprecedented spatial resolution ofChandra with the soft XMM-Newton response, we will obtain a census of X-raybinaries, probe the nature of accreting sources, and find hot bubbles in thistemplate low-metallicity galaxy. New Chandra observations will complement theHST observations of massive stars in NGC3109. Obtaining first robustmeasurements of X-ray sources in NGC3109 is a necessary next step to progress inour understanding of massive binary star evolution and feedback atlow-metallicities and, by proxy, in early cosmic times.

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.
