|Title||A Complete Census Compton-thick AGN in the local Universe from Swift BAT|

|Description||Heavily obscured accretion is believed to be an extremely important phase in the growth of supermassive black holes, and to produce a signi cant fraction of the Cosmic X-ray background. Studying in detail the broad-band X-ray emission of the 830 AGN reported in the 70-months Swift-BAT catalog, we found evidence of CT obscuration in 55 objects, which makes this the largest sample of CT AGN in the local Universe. We propose to observe the remaining 10-55 sources which lack an XMM-Newton or Suzaku observation as a ful l program. These observations will constrain the brightest end of the luminosity function of CT AGN and the evolution of the covering factor of the CT material, besides serving as a benchmark to study luminous CT AGN at higher redshifts.|

|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.
