      Del Carmen Polletta, Maria; Wilkes, Belinda J.; Siana, Brian D.; Lonsdale, Carol J.; Kilgard, Roy E.; Smith, Harding E.; Kim, Dongwoo; Owen, Frazer N.; Efstathiou, Andreas; Jarrett, Thomas H.M.; Stacey, Gordon J.; Franceschini, Alberto; Rowan-Robinson, Michael; Babbedge, Tom S.R.; Berta, Stefano; Fang, Fan; Farrah, Duncan G.; González-Solares, Eduardo A.; Morrison, Glenn E.; Surace, Jason A.; Shupe, David L. (2006-05-10)
      Using the large multiwavelength data set in the Chandra/SWIRE Survey (0.6 deg2 in the Lockman Hole), we show evidence for the existence of highly obscured (Compton-thick) AGNs, estimate a lower limit to their surface ...
