Is There a Disc in the Superluminal Quasars?
arXiv:astro-ph/0301405 · doi:10.1046/j.1365-8711.2003.06414.x
Abstract
We present a new evidence of the accretion disc in active galactic nuclei, by examining the properties of the Ha emission line versus viewing angle, in a sample of superluminal (SL) quasars. Both line velocity width (FWHM) and rest equivalent width (EW) correlate with viewing angle. These correlations are quantitatively consistent with a disc geometry for both the line and the underlying continuum source.
