    • Chandra and spitzer unveil heavily obscured quasars in the chandra/swire survey 

      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 ...
    • Direct evidence for termination of obscured star formation by radiatively driven outflows in reddened QSOs 

      Farrah, Duncan G.; Urrutia, Tanya; Lacy, Mark D.; Efstathiou, Andreas; Afonso, José M.; Coppin, Kristen E.K.; Hall, Patricke B.; Lonsdale, Carol J.; Jarrett, Thomas H.M.; Bridge, Carrie R.; Borys, Colin J.K.; Petty, Sara M. (2012-02-01)
      We present optical to far-infrared photometry of 31 reddened QSOs that show evidence for radiatively driven outflows originating from active galactic nuclei (AGNs) in their rest-frame UV spectra. We use these data to study ...
    • RADIO JET FEEDBACK and STAR FORMATION in HEAVILY OBSCURED, HYPERLUMINOUS QUASARS at REDSHIFTS ∼ 0.5-3. I. ALMA OBSERVATIONS 

      Lonsdale, Carol J.; Lacy, Mark D.; Kimball, Amy E.; Blain, Andrew W.; Whittle, Mark; Wilkes, Belinda J.; Stern, Daniel K.; Condon, James J.; Kim, Minjin; Assef, Roberto J.; Tsai, Chao Wei; Efstathiou, Andreas; Jones, Suzy F.; Eisenhardt, Peter R.M.; Bridge, Carrie R.; Wu, Jingwen; Lonsdale, Colin J.; Jones, Kevin M.; Jarrett, Thomas H.M.; Smith, Rory Fiona (2015-11-01)
      We present Atacama Large Millimeter/submillimeter Array (ALMA) 870 μm (345 GHz) data for 49 high-redshift (0.47 < z < 2.85), luminous (11.7 < log(Lbol/L⊙) < 14.2) radio-powerful active galactic nuclei (AGNs), obtained to ...
    • The role of the most luminous obscured AGNs in Galaxy assembly at Z ∼ 2 

      Farrah, Duncan G.; Petty, Sara M.; Connolly, Brian; Blain, Andrew W.; Efstathiou, Andreas; Lacy, Mark D.; Stern, Daniel K.; Lake, Sean E.; Jarrett, Thomas H.M.; Bridge, Carrie R.; Eisenhardt, Peter R.M.; Benford, Dominic J.; Jones, Suzy F.; Tsai, Chao Wei; Assef, Roberto J.; Wu, Jingwen; Moustakas, Leonidas A. (2017-01-01)
      We present Hubble Space Telescope WFC3 F160W imaging and infrared spectral energy distributions for 12 extremely luminous, obscured active galactic nuclei (AGNs) at 1.8 < z < 2.7 selected via “hot, dust-obscured” mid-infrared ...
