Does the Narrow [ O III ] λ 5007 Line Reflect the Stellar Velocity Dispersion in AGN ?

Abstract

It has been proposed that the width of the narrow [O III] λ5007 emission line can be used as a surrogate for the stellar velocity dispersion in active galaxies. This proposition is tested using the SDSS EDR spectra of 107 low-redshift radio-quiet QSOs and Seyfert 1 galaxies by investigating the correlation between black hole mass, as determined from Hβ FWHM… (More)
