H, He-like recombination spectra IV; H, He-like recombination spectra IV: clarification and refinement of methodology for -changing collisions
N. R. Badnell, F. Guzmán, S. Brodie +4
Precise spectral diagnostic modelling of H~{\sc i} and He~{\sc ii} recombination spectra can constrain theoretical models which describe many astrophysical environments. Simple ana…
High-ionization emission line ratios from quasar broad line regions: metallicity or density?
Matthew J. Temple, Gary J. Ferland, Amy L. Rankine +2
The flux ratios of high-ionization lines are commonly assumed to indicate the metallicity of the broad emission line region in luminous quasars. When accounting for the variation i…
X-ray spectroscopy in the microcalorimeter era III: line formation under Case A, Case B, Case C, and Case D in H- and He-like iron for a photoionized cloud
Priyanka Chakraborty, Gary Ferland, Marios Chatzikos +2
Future microcalorimeter X-ray observations will resolve spectral features in unmatched detail. Understanding the line formation processes in the X-rays deserves much attention. The…
