| Description | The well-established X-ray-FIR luminosity correlation suggests that X-ray luminosity may be a star-formation rate (SFR) indicator. However recent work has shown that there is some uncertainty concerning the slope and normalization of X-ray-SFR correlation. It is likely that the variation observed is due in part to biases in the samples studied to date. We propose to observe an optically-selected, local sample of galaxies to determine the X-ray-SFR correlation in an unbiased fashion, using extinction-corrected H-alpha luminosities, the "gold standard" SFR indicator. The precise value of this correlation will be a constraint on galaxy evolution models, particularly concerning the evolution of massive stars and the efficiency of heating the ISM. |

| Mission Description | 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. |
