Description This proposal aims at confirming our claim that high X-ray luminosity normal galaxies, discovered in deep XMM-Newton and Chandra surveys and classified as new classes of exotic objects (OLEGs, Fossil Groups, XBONGs, Elusive AGNs.), were already present in earlier and much brighter samples. We argue that these .unusual. populations are actually the low-flux counterparts of the nearby and X-ray bright galaxies that have been known for the last two decades. We propose to observe an X-ray flux limited sample from the EMSS high Lx normal galaxies to derive their detailed spectral and morphological properties, to determine a reliable estimate of the number density of the population, and to provide a statistical basis for classifying the objects found in deeper surveys.

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.
