    • A comparative HST imaging study of the host galaxies of radio-quiet quasars, radio-loud quasars and radio galaxies: I 

      McLure, Ross; Dunlop, James; Kukula, Marek; Baum, Stefi; O'Dea, Christopher; Hughes, David (Blackwell Publishing, 1999-09)
      We present the first results from a major HST WFPC2 imaging study aimed at providing the first statistically meaningful comparison of the morphologies, luminosities, scalelengths and colours of the host galaxies of radio-quiet ...

    • Exploring the variable sky with the Sloan Digital Sky Survey 

      Sesar, Branimir; Ivezic, Zeljko; Lupton, Robert; Juric, Mario; Gunn, James; Knapp, Gillian; De Lee, Nathan; Smith, Allyn; Miknaitis, Gajus; Lin, Huan; Tucker, Douglas; Doi, Mamoru; Tanaka, Masayuki; Fukugita, Masataka; Holtzman, Jon; Kent, Steve; Yanny, Brian; Schlegel, David; Finkbeiner, Douglas; Padmanabhan, Nikhil; Rockosi, Constance; Bond, Nicholas; Lee, Brian; Stoughton, Chris; Jester, Sebastian; Harris, Hugh; Harding, Paul; Brinkmann, Jon; Schneider, Donald; York, Donald; Richmond, Michael; Vanden Berk, Daniel (American Astronomical Society - The Astronomical Journal, 2007-12)
      We quantify the variability of faint unresolved optical sources using a catalog based on multiple SDSS imaging observations. The catalog covers SDSS Stripe 82, which lies along the celestial equator in the Southern ...

    • The host galaxies of luminous quasars 

      Floyd, David; Kukula, Marek; Dunlop, James; McLure, Ross; Miller, Lance; Percival, Will; Baum, Stefi; O'Dea, Christopher (Blackwell Publishing, 2004-11)
      We present the results of a deep HST/WFPC2 imaging study of 17 quasars at z~=0.4, designed to determine the properties of their host galaxies. The sample consists of quasars with absolute magnitudes in the range −24 ≥ MV ...

    • A large, uniform sample of X-ray emitting AGN from the ROSAT All-Sky and Sloan Digital Sky Surveys: the Data Release 5 Sample 

      Anderson, Scott; Margon, Bruce; Voges, Wolfgang; Plotkin, Richard; Syphers, David; Haggard, Daryl; Collinge, Matthew; Meyer, Jillian; Strauss, Michael; Agueros, Marcel; Hall, Patrick; Homer, Lee; Richards, Gordon; Richmond, Michael; Schneider, Donald; Stinson, Gregory; Vanden Berk, Daniel; York, Donald (American Astronomical Society - The Astronomical Journal, 2003-11)
      We describe further results of a program aimed to yield ∼104 fully characterized optical identifications of ROSAT X-ray sources. Our program employs X-ray data from the ROSAT All-Sky Survey (RASS), and both optical imaging ...

    • A large, uniform sample of X-ray emitting AGN: selection approach and an initial catalog from the ROSAT All-Sky and Sloan Digital Sky Surveys 

      Anderson, Scott; Voges, Wolfgang; Margon, Bruce; Trumper, Joachim; Agueros, Marcel; Boller, Thomas; Collinge, Matthew; Homer, Lee; Stinson, Gregory; Strauss, Michael; Annis, James; Gomez, Percy; Hall, Patrick; Nichol, Robert; Richards, Gordon; Schneider, Donald; Vanden Berk, Daniel; Fan, Xiaohui; Ivezic, Zeljko; Munn, Jeffrey; Newberg, Heidi Jo; Richmond, Michael; Weinberg, David; Yanny, Brian; Bahcall, Neta; Brinkmann, Jonathan; Fukugita, Masataka; York, Donald (American Astronomical Society - The Astronomical Journal, 2003-11)
      Many open questions in X-ray astronomy are limited by the relatively small number of objects in uniform optically-identified and observed samples, especially when rare subclasses are considered, or when subsets are ...
