Finding Compton-thick AGN Among the Faintest Swift BAT Sources

We propose short XMMNewton observations of 8 sources newly detected in thedeepest SwiftBAT 104 month stacked allsky maps, but for which a Swift XRTobservation has detected no Xray counterpart. Our past studies of these faintBAT sources found some of the brightest examples of reflectiondominated AGNavailable across the sky with accretion rates several times higher than typicalAGN that contribute significantly to black hole growth in the nearby universe.XMMNewton 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(FWHM22.5arcmin). truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
