J/ApJ/549/155       [OIII] emission in a sample of AGNs     (Nagao+, 2001)

Where is the [O III] λ4363 emitting region in active galactic nuclei? Nagao T., Murayama T., Taniguchi Y. <Astrophys. J., 549, 155-171 (2001)> =2001ApJ...549..155N
ADC_Keywords: Active gal. nuclei ; QSOs ; Infrared sources Keywords: galaxies: active - galaxies: nuclei - galaxies: Seyfert - quasars: emission lines Abstract: The emission-line flux ratio of [OIII]4363/[OIII]5007 (ROIII) is a useful diagnostic for the ionization mechanism and physical properties of emission-line regions in active galactic nuclei (AGNs). However, it is known that simple photoionization models underpredict the [OIII]4363 intensity, being inconsistent with observations. In this paper we report on several pieces of evidence that a large fraction of the [OIII]4363 emission arises from the dense gas obscured by putative tori: (1) the visibility of high-ROIII regions is correlated to that of broad-line regions, (2) higher ROIII objects show hotter mid-infrared colors, (3) higher ROIII objects show stronger highly ionized emission lines such as [FeVII] 6087 and [FeX]6374, and (4) higher ROIII objects have broader line width of [OIII]4363 normalized by that of [OIII]5007.
