Description Using the SDSS, we have identified a large number of type II quasars (high-luminosity obscured AGN, with L_bol > 10^45 ergs-s) at redshift z < 0.8. We are conducting a comprehensive multi-wavelength follow-up of the most luminous objects in the sample. We propose to continue our survey of type II quasars with XMM to obtain a large sample of objects with known X-ray properties. Our primary goal is to quantify their degree of obscuration. We also will study the statistical properties of quantities such as X-ray spectral slope and L_X-L[OIII] relative to Seyfert 2 galaxies and for the first time determine the distribution of the absorbing column densities among the luminous type II quasars.

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.
