Title: Does the Narrow [O III]\lambda5007
Line
Reflect the Stellar
Velocity Dispersion in AGN?
Abstract:
It has been proposed that the width of the narrow [O III] \lambda5007 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
radioquiet
QSOs and Seyfert 1 galaxies by investigating the correlation between black
hole mass, as determined from H\Beta FWHM and optical luminosity, and [O III]
FWHM. The correlation is real, but the scatter is large. Without additional
information or selection criteria, the [O III] width can predict the black
hole
mass to a factor of 5.
