cds-question@unistra.fratomic-physicsThe Fe unresolved transition arrays (UTAs) produce prominent features in the ~15-17{AA} wavelength range in the spectra of active galactic nuclei (AGNs). Here, we present new calculations of the energies and oscillator strengths of inner-shell lines from FeXIV, FeXV, and FeXVI. These are crucial ions since they are dominant at inflection points in the gas thermal stability curve, and UTA excitation followed by autoionization is an important ionization mechanism for these species. We incorporate these, and data reported in previous papers, into the plasma simulation code Cloudy. This updated physics is subsequently employed to reconsider the thermally stable phases in absorbing media in AGNs. We show how the absorption profile of the Fe XIV UTA depends on density, due to the changing populations of levels within the ground configuration.2013ApJ...767..123Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/767/123CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/207/11 : Fe XVI radiative rates (Diaz+, 2013)J/A+A/543/A144 : Fe XIII soft X-ray lines (Del Zanna+, 2012)J/ApJS/190/322 : R-matrix electron-impact excitation of Fe^13+^ (Liang+, 2010)J/A+A/511/A78 : Fe XIII electron impact excitation (Storey+, 2010)J/A+A/463/399 : Fe XVI radiative rates (Aggarwal+, 2007)J/A+A/450/1249 : Fe XVI radiative and excitation rates (Aggarwal+, 2006)J/A+A/429/1117 : Fe XIII effective collision strengths (Aggarwal+, 2005)J/A+A/418/371 : Electron impact excitation of Fe XIII (Aggarwal+, 2004)J/A+A/414/377 : FeX-FeXVII fine-structure K-vacancy levels (Mendoza+, 2004)J/A+A/410/349 : Effective collision strengths in Fe XV (Aggarwal+, 2003)J/A+AS/137/165 : IRON Project XXXVIII.
