| Abstract | We propose short XMM-Newton observations of 8 sources newly detected in thedeepest Swift-BAT 104- month stacked all-sky maps, but for which a Swift XRTobservation has detected no X-ray counterpart. Our past studies of these faintBAT sources found some of the brightest examples of reflection-dominated AGNavailable across the sky with accretion rates several times higher than typicalAGN that contribute significantly to black hole growth in the nearby universe.XMM-Newton is critical to identify these sources because of the factor of >10xhigher sensitivity than Swift XRT combined with a very large FOV (28.4arcsec) toresolve any contributing sources associated with Swift BAT detection(FWHM=22.5arcmin). |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
