abstract

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

  1. Direct VLBI evidence for a buried AGN in the triple-merger LIRG UGC 2369S

    astro-ph.GA 2026-07 unverdicted novelty 4.0 of 10

    VLBI imaging detects a compact radio source with Tb > 10^7 K and flat spectrum in the northern core of UGC 2369S, confirming a buried low-luminosity AGN.
