A Model for Type 2 Coronal Line Forest (CLiF) AGN
  We present a model for the classification of Coronal-Line Forest Active
Galactic Nuclei (CLiF AGN). CLiF AGN are of special interest due to their
remarkably large number of emission lines, especially forbidden high ionization
lines (FHILs). Rose et al. (2015a) suggest that their emission is dominated by
reflection from the inner wall of the obscuring region rather than direct
emission from the accretion disk. This makes CLiF AGN laboratories to test
AGN-torus models. Modeling AGN as an accreting supermassive black hole,
surrounded by a cylinder of dust and gas, we show a relationship between
viewing angle and the revealed area of the inner wall. From the revealed area,
we can determine the amount of FHIL emission at various angles. We calculate
the strength of [FeVII]{\lambda}6087 emission for a number of intermediate
angles (30$^{\circ}$, 40$^{\circ}$, and 50$^{\circ}$) and compare the results
with the luminosity of the observed emission line from six known CLiF AGN. We
find that there is good agreement between our model and the observational
results. The model also enables us to determine the relationship between the
type 2 : type 1 AGN fraction vs the ratio of torus height to radius, h/r.
