|FAINT X-RAY SOURCES IN NEARBY DWARF SPHERIOD GALAXIES
|Dr GAVIN RAMSAY
|The study of X-ray sources in large external galaxies has been vigorously pursued in recent years, allowing a global analysis of their populations along the Hubble sequence. We aim to extend this analysis to dwarf spheroidal galaxies. The aim of this proposal is to characterise the X-ray population of the Sagittarius and Carina dwarf galaxies. The Carina dwarf has a more complex and recent star formation history compared to Sagittarius. The aims of our project is to improve our understanding of the episodal star formation history of these systems which will serve as a comparison with large, normal galaxies.

|The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
