Hidden quasars in ultraluminous infared galaxies

Conference ·
OSTI ID:3392
Abstract. Many ultraluminous infrared galaxies (ULIRGS) are pow- ered by quasars hidden in the center, but many are also powered by starbursts. A simply diagnostic diagram is proposed that can iden- tify obscured quasars in ULIRGs by their high-ionization emission lines ([O III]λ5007/Hβ ≳ 5), and "warm" IR color (ƒ2560 ≳ 0.25).
