Analysis of broad-line regions in AGNs
Listed in IVOA Registry (Virtual Observatory)
A two-component model for the broad-line region (BLR) of active galactic nuclei (AGNs) has been suggested for many years but not widely accepted.
Description
This model indicates that the broad line can be described with the superposition of two Gaussian components (very broad Gaussian component (VBGC) and intermediate Gaussian component (IMGC)) which are from two physically distinct regions, i.e., very broad line region (VBLR) and intermediate line region.
We select a Sloan Digital Sky Survey sample to further confirm this model and give a detailed analysis of the geometry, density, and evolution of these two regions.
