Description GT-Active Galactic Nuclei with heavily absorbed X-ray spectra are one of the best class of candidate objects to explain the bulk of the energy density of the X-ray background. These objects should also be significantly absorbed in the optical. One of the still open questions is, how much high luminosity absorbed AGN (i.e. type II QSOs) contribute to the XRB. We therefore propose to observe a sample of broad-absorption line QSOs with XMM.

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.
