An Empirical Temperature Relation for Chemical Abundances in AGN
Sophia R. Flury, Oli L. Dors, Rogemar A. Riffel +5
We present for the very first time the empirical temperature structure of the narrow line region (NLR) clouds of active galactic nuclei (AGNs) based on a sample of [N II] and [O II…
Identifying AGNs from X-ray detectionsII: Metallicity calibrations for the and diagnostics
Mark Armah, O. L. Dors, Rogério Riffel +4
Emission-line ratios from ions with nearly identical ionization potentials offer a robust solution to the degeneracies inherent to traditional active galactic nuclei (AGNs) metalli…
Identifying AGNs from X-ray detections-I: Metallicity calibrations in AGNs with X-ray luminosity as the primary input parameter
Mark Armah, O. L. Dors, Rogério Riffel +4
We present the first semi-empirical strong-line calibrations to determine metallicity in Active Galactic Nuclei (AGNs) that use the directly observable X-ray luminosity (Lx) instea…
