    • Testing Models for the Quasar Big Blue Bump via Color-Color Diagrams 

      Siemiginowska, Aneta L.; Kuhn, Olga; Elvis, Martin S.; Fiore, Fabrizio; McDowell, Jonathan Christopher; Wilkes, Belinda Jane (IOP Publishing, 1995)
      We discuss several models of quasar big blue bump emission in color-color and color-luminosity diagrams. We define several broad passbands: IR (0.8-1.6 μm), VIS (4000-8000 Å), UV (1000-2000 Å), UV1 (1400-2000 Å) and UV2 ...
