The Profiles of H-Beta and [OIII] 5007 in Radio-Loud Quasars
Abstract
Moderate-resolution spectra of the Hβ--[O III] λ5007 region have been obtained for 41 radio-loud quasars in order to investigate relationships among their broad- and narrow-line profiles, radio structures, and X-ray properties. Spectra from the literature have been included to form a data set of 60 radio-loud quasars. A variety of statistical analyses have been performed, identifying several strong, related trends. The FWHM, equivalent width, and degree of redward asymmetry of Hβ increase with decreasing radio core dominance (an orientation indicator), whereas the FWHM of [O III] λ5007 increases with luminosity and αox. These and other effects are briefly discussed.
