Abstract | Studies of star formation in the distant (z gt 1) Universe are largely confinedto the rest-frame ultraviolet. The best-studied UV-selected galaxies are theLyman Break galaxies (LBGs), whose X-ray properties have been determined viastatistical/stacking analyses of large samples of galaxies in long effectiveChandra exposures (gt 30 Ms). There is a new opportunity to study LBGs: therecently-launched GALEX survey mission has selected a low-redshift LBGpopulation: the UV Luminous Galaxies (UVLGs). Although these galaxies aretypically at z lt 0.3 they are sufficiently distant that their X-ray fluxes arefairly low. With 242 ks of XMM time, we will determine the individual X-rayproperties of eight LBGs and put the X-ray/SFR correlation on firmer footing. |

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. |
