Dust Obscured Quasars

Francis, Paul; Webster, Rachel J.; Peterson, Bruce A.; Drinkwater, Michael J.; Masci, Frank J.


We find that nearly all radio-loud, flat spectrum quasars are obscured by a magnitude or more of dust. The dust is probably located in the quasar or its host galaxy. If radio-quiet QSOs have comparable amounts of dust, ∼ 80% have been missed by all existing surveys. These missing QSOs may explain the X-ray background.
