Hidden quasars in ultraluminous infared galaxies

PDF Version Also Available for Download.

Description

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 ([0 III]X5007/HP ,? 5), and �warm� IR color (&/f6s 2 0.25).
