cds-question@unistra.fractive-galactic-nucleispectroscopyline-intensitiesWe introduce Coronal-Line Forest active galactic nuclei (CLiF AGN), AGN which have a rich spectrum of forbidden high-ionization lines (FHILs, e.g. [FeVII], [FeX] and [NeV]), as well as relatively strong narrow (~300 km/s) H{alpha} emission when compared to the other Balmer transition lines. We find that the kinematics of the CLiF emitting region are similar to those of the forbidden low-ionization emission-line (FLIL) region. We compare emission line strengths of both FHILs and FLILs to cloudy photoionization results and find that the CLiF emitting region has higher densities (10^4.5^<n_H_<10^7.5^/cm^3^) when compared to the FLIL emitting region (10^3.0^<n_H_<10^4.5^/cm^3^). We use the photoionization results to calculate the CLiF regions radial distances (0.04<R_CLiF_<32.5 pc) and find that they are comparable to the dust grain sublimation distances (0.10<R_SUB_<4.3 pc). As a result, we suggest that the inner torus wall is the most likely location of the CLiF region, and the unusual strength of the FHILs is due to a specific viewing angle giving a maximal view of the far wall of the torus without the continuum being revealed.2015MNRAS.448.2900Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/448/2900CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/270 : SDSS quasar catalog: tenth data release (Paris+, 2014)J/ApJS/143/257 : AGN emission line properties (Kuraszkiewicz+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/448/2900https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/448/2900http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/448/2900https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/448/2900https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/448/2900http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/448/2900GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/448/2900/table1 (Basic properties of the CLiF AGN sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/448/2900/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/448/2900/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/448/2900/table1?GETtext/xml+votable180.050000true222.657708322.73433610.0055555555555555566/8992 9646 9812 109482.85864675833786e-19 3.5010283109654867e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/448/2900?format=asciiOpticaldefaultJ/MNRAS/448/2900/table1Basic properties of the CLiF AGN sampleSimbadNameSimbad column added by the CDSmeta.idcharzRedshift (1)src.redshiftfloatrecnoRecord number assigned by the VizieR team.
