Description Accretion is recognized to play a significant role in galaxy evolution. Theory predict the existence of deeply buried AGN. The cosmic X-ray background strongly supports the existence of very absorbed, Compton-thick AGN; however, very few of them have been detected in hard X-ray surveys. We propose to observe 6 very good Compton-thick candidates detected in the deepest extragalactic survey performed by INTEGRAL. These sources have been confirmed in short Chandra observations. Their hard-to-medium X-ray flux ratios are larger by a factor 5-10 than those expected for an unabsorbed, G=1.9 power law. These observations will very strongly constrain the fraction of Compton-thick AGN at the faintest hard X-ray fluxes, making a stringent test of X-ray background synthesis models.

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.
