    • 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 ...
    • Two more candidate AM Canum Venaticorum (AM CVn) Binaries from the Sloan Digital Sky Survey 

      Anderson, Scott; Becker, Andrew; Haggard, Daryl; Prieto, Jose Luis; Knapp, Gillian; Sako, Masao; Halford, Kelly; Jha, Saurabh; Martin, Blake; Holtzman, Jon; Frieman, Joshua; Garnavich, Peter; Hayward, Suzanne; Ivezic, Zeljko; Mukadam, Anjum; Sesar, Branimir; Szkody, Paula; Malanushenko, Viktor; Richmond, Michael; Schneider, Donald; York, Donald (American Astronomical Society - The Astronomical Journal, 2008-06)
      AM CVn systems are a select group of ultracompact binaries with the shortest orbital periods of any known binary subclass; mass-transfer is likely from a low-mass (partially-)degenerate secondary onto a white dwarf ...
    • Ultracompact AM CVn Binaries from the Sloan Digital Sky Survey: three candidates plus the first confirmed Eclipsing System 

      Anderson, Scott; Haggard, Daryl; Homer, Lee; Joshi, Nikhil; Margon, Bruce; Silvestri, Nicole; Szkody, Paula; Wolfe, Michael; Agol, Eric; Becker, Andrew; Henden, Arne; Hall, Patrick; Knapp, Gillian; Richmond, Michael; Schneider, Donald; Stinson, Gregory; Barentine, John; Brewington, Howard; Brinkmann, Jonanthan; Harvanek, Michael; Kleinman, Scott; Krzesinski, Jurek; Long, Dan; Neilsen, Eric; Nitta, Atsuko; Snedden, Stephanie (American Astronomical Society - The Astronomical Journal, 2005-11)
      AM CVn systems are a rare (about a dozen previously known) class of cataclysmic variables, arguably encompassing the shortest orbital periods (down to about 10 minutes) of any known binaries. Both binary components are ...
