J/AJ/130/381       Blueshifted [O III] emission                 (Boroson+, 2005)

Blueshifted [O III] emission: indications of a dynamic narrow-line region. Boroson T. <Astron. J., 130, 381-386 (2005)> =2005AJ....130..381B
ADC_Keywords: Active gal. nuclei ; Redshifts ; Galaxies, spectra Keywords: galaxies: active - galaxies: Seyfert - quasars: emission lines Abstract: The [OIII]λ5007 line is commonly used as an indicator of the systemic redshift of active galactic nuclei (AGNs). Also, recent studies have used the width of this emission line as a proxy for the stellar velocity dispersion in the host galaxy. This paper calls both of these assumptions into question by analyzing a sample of approximately 400 AGN spectra from the first data release of the Sloan Digital Sky Survey. File Summary:

Note (1): Subsample, defined as follows: B = [OIII] velocities from the moderately blueshifted region N = [OIII] velocities are in good agreement with the systemic redshift N-NLS1 = [OIII] velocities near zero R = [OIII] velocities from the most redshifted extreme of the distribution VB = [OIII] velocities from the most blueshifted extreme of the distribution
