Abstract The well-established X-ray/FIR luminosity correlation suggests that X-rayluminosity may be a star-formation rate (SFR) indicator. However recent work hasshown that there is some uncertainty concerning the slope and normalization ofX-ray/SFR correlation. It is likely that the variation observed is due in partto biases in the samples studied to date. We propose to observe anoptically-selected, local sample of galaxies to determine the X-ray/SFRcorrelation in an unbiased fashion, using extinction-corrected H-alphaluminosities, the gold standard SFR indicator. The precise value of thiscorrelation will be a constraint on galaxy evolution models, particularlyconcerning the evolution of massive stars and the efficiency of heating the ISM.

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.
