Gary J. Ferland,R. L. Porter,P. A. M. van Hoof,R. J. R. Williams,N. P. Abel,Matt L. Lykins,Gargi Shaw,William J. Henney,Phillip C. Stancil +8 more
TL;DR: Cloud as discussed by the authors models the ionization, chemical, and thermal state of material that may be exposed to an external radiation field or other source of heating, and predicts observables such as emission and absorption spectra.

The 2013 Release of Cloudy
Gary J. Ferland,R. L. Porter,P. A. M. van Hoof,R. J. R. Williams,N. P. Abel,Matt L. Lykins,Gargi Shaw,William J. Henney,Phillip C. Stancil +8 more
TL;DR: Cloud as mentioned in this paper models the ionization, chemical, and thermal state of material that may be exposed to an external radiation field or other source of heating, and predicts observables such as emission and absorption spectra.
Journal ArticleDOI
Collisional heating as the origin of filament emission in galaxy clusters

TL;DR: In this paper, the authors extended the results of Wrathmall et al. to include atomic and low-ionization regions and showed that these regions are often much larger and allow the ro-vibrational H2 level populations to achieve a thermal distribution at substantially lower densities than previously thought.
Journal ArticleDOI
The primordial helium abundance from updated emissivities
TL;DR: In this paper, Izotov et al. used a Markov Chain Monte Carlo analysis to determine the primordial helium abundance in the extragalactic H II regions of the Earth.
Journal ArticleDOI
Erratum: 'Improved He I emissivities in the Case B approximation'
TL;DR: Porter et al. as discussed by the authors discovered errors in their recent calculations of HeI emissivities and reported corrected emissivity values, and discussed the errors in a corrigendum.
