| 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 of at least 4E-14 ergs/cm2/s. This sample has approved Spitzer spectroscopic observations and each galaxy 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, providing new insights into AGN physics. |

| 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. |
