Gary J. Ferland,Marios Chatzikos,F. Guzmán,Matt L. Lykins,P. A. M. van Hoof,R. J. R. Williams,N. P. Abel,N. R. Badnell,Francis P. Keenan,R. L. Porter,Phillip C. Stancil +10 more
TL;DR: The 2017 version of Cloudy as mentioned in this paper is the most recent version of the spectral synthesis code, which has made many improvements to the scope and accuracy of the physics which have been made since the previous release.

Implications of Infalling Fe II-Emitting Clouds in Active Galactic Nuclei: Anisotropic Properties
Gary J. Ferland,Chen Hu,Jian-Min Wang,Jack A. Baldwin,R. L. Porter,Peter A. M. van Hoof,R. J. R. Williams +6 more
TL;DR: In this article, it was shown that Eigenvector 1 correlates with the Eddington ratio L/L(Edd) so that Fe II/H beta increases as L/l(Edding) increases.
Journal ArticleDOI
Theoretical He I Emissivities in the Case B Approximation
TL;DR: In this paper, the He I case B recombination cascade spectrum was calculated using improved radiative and collisional data and new emissivities over a range of electron temperatures and densities.
Journal ArticleDOI
He I Emission in the Orion Nebula and Implications for Primordial Helium Abundance
TL;DR: In this article, the authors apply a recently developed theoretical model of helium emission to observations of both the Orion Nebula and a sample of extragalactic H II regions and find an average difference between theoretical and observed intensities Ipred/Iobs? 1 = 6.5%.
Journal ArticleDOI
Improved He I Emissivities in the Case B Approximation
TL;DR: In this paper, a large set of accurate, self-consistent cross-sections represents a significant improvement in He I emissivity calculations because it largely obviates the piecemeal nature that has marked all modern works.
