Description We propose to obtain XMM-Newton data for a complete sample of the 20 brightest Type 2 AGN drawn from virgul100000 low-z AGN in the SDSS DR4. The sample members have a flux in the [OIII]5007 emission line > 4x10E-14 erg-(cm^2 s). Each has a wealth of information about the AGN and its host galaxy derived homogeneously from the SDSS (including the black hole mass, [OIII] luminosity, and Eddington ratio for the AGN and the mass, structure, and stellar content of the galaxy). We will use these combined data to determine the fraction of Compton-thick AGN and to determine whether they differ systematically in terms of the properties of the AGN and the host galaxy. This will provide new insights into AGN physics, the evolution of galaxies and black holes, and the hard X-ray background.

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.
