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…

A bayesian-like approach to derive chemical abundances in Type-2 Active Galactic Nuclei based on photoionization models
E. Pérez-Montero, O. L. Dors, J. M. Vílchez +3
We present a new methodology for the analysis of the emission lines of the interstellar medium in the Narrow Line Regions around type-2 Active Galactic Nuclei. Our aim is to provid…

The interstellar medium of dwarf galaxies: new insights from Machine Learning analysis of emission line spectra
Graziano Ucci, Andrea Ferrara, Simona Gallerani +6
Dwarf galaxies are ideal laboratories to study the physics of the interstellar medium (ISM). Emission lines have been widely used to this aim. Retrieving the full information encod…
