cds-question@unistra.fractive-galactic-nucleiastronomical-modelsspectroscopyA two-component model for the broad-line region (BLR) of active galactic nuclei (AGNs) has been suggested for many years but not widely accepted. 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.2009ApJ...700.1173Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/700/1173CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/613/682 : AGN central masses and broad-line region sizes (Peterson+,J/ApJ/660/1072 : Unified model of active galactic nuclei (Wang+, 2007)J/MNRAS/383/581 : Broad-line Balmer decrements in blue AGN (Dong+, 2008)J/ApJ/690/20 : Models of the AGN and black hole populations (Shankar+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/700/1173https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/700/1173http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/700/1173https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/700/1173https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/700/1173http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/700/1173GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/700/1173/table1 (Source properties and decomposition parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/700/1173/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/700/1173/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/700/1173/table1?GETtext/xml+votable180.050000true178.1458311-0.09520170.0055555555555555566/2 4144 5721 6028 6087 6097 6211 6417 6526 6534 7211 7230 7247 7361 8216 9612 9733 9796 9811 9812 9930 10092 10188 10191 10680 11103 11204 11388 11473 11585 11872 11906 16894 17254 17507 17562 17742 17756 17822 17827 17830 17832 18001 18009 18011 18070 18093 18302 18367 18769 18771 21885 22762 23064 23203 23209 23211 23216 25968 25992 26017 26019 26022 26041 26191 26225 26300 26310 26316 26369 26965 26966 26990 26998 27032 27033 27224 27249 27293 27411 27472 27654 27663 27821 31397 31404 49097https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/700/1173?format=asciidefaultJ/ApJ/700/1173/table1Source properties and decomposition parametersrecnoRecord number assigned by the VizieR team.
