Galactic outflows play an important role in regulating the rate of starformation as well as in the chemical evolution of galaxies. We plan to observethe X-ray emission from two starbursts in two collisional ring galaxies (theCartwheel Galaxy and AM0644-741) that have similar star formation rates butdifferent metallicities. Massive star formation is confined to an outer annularring, not a starburst galaxy nucleus, allowing for accurate measurements oftemperature and luminosity. We will determine how the outflow.s temperatures andmetallicities depend on the intrinsic metallicity of the host galaxy.s ISM, aswell as constrain the relative contributions of HMXB and hot gas to the totalX-ray emission. XMM-Newton.s high sensitivity is crucial to achieve these goals.

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.
