Finding All Compton-thick AGN in the Swift BAT 105-month Sky Survey

We propose short XMM observations of sources detected in the deepest SwiftBAT105month stacked all sky maps, but for which a Swift XRT observation has noobvious Xray counterpart. Our past studies of these faint BAT sources foundsome of the brightest examples of reflectiondominated AGN in the sky withaccretion rates several times higher than typical AGN that contributesignificantly to black hole growth in the nearby universe. This study will haveenduring legacy value by completing the counterpart association for the full105month allsky catalog outside of the Galactic plane (|b|>10). XMM iscritical to identify these sources because of the factor of 13X highersensitivity than Swift XRT combined with a very large FOV (28.4.) to resolve any contributing sources. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
