|Title||Revealing the most highly-accreting CT AGN in the local Universe with XMM-Newton|
|Author||Dr Claudio Ricci|
|Description||Heavily obscured accretion is believed to be an extremely important phase in the growth of supermassive black holes. However, so far only a few CT AGN are known in the local Universe, and most of them have luminosities log(Lx) < 44.4. We propose here to observe the 5 most luminous CT AGN at redshift z <0.2 with no high-quality 0.3-10keV observation available. This will increase the sample of local high-luminosity CT AGN by a factor of 3.5, greatly improving our knowledge of CT obscuration at the highest accretion rates. These observations will allow to 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.
