Metallicity of Active Galactic Nuclei from ultraviolet and optical emission lines-II. Revisiting the metallicity calibration and its implications
O. L. Dors, C. B. Oliveira, M. V. Cardaci +7
In this study, a new semi-empirical calibration is proposed between ultraviolet emission lines (\ion{C}{iii}], \ion{C}{iv}, \ion{He}{ii}]) of…
Metallicity of Active Galactic Nuclei from ultraviolet and optical emission lines I: Carbon abundance dependence
O. L. Dors, C. B. Oliveira, M. V. Cardaci +9
Metallicity () estimates based on ultraviolet (UV) emission lines from the narrow-line regions (NLRs) of active galactic nuclei (AGNs) have been found to differ from those deriv…
BASS XLI: the correlation between Mid-infrared emission lines and Active Galactic Nuclei emission
M. Bierschenk, C. Ricci, M. J. Temple +22
We analyze the Spitzer spectra of 140 active galactic nuclei (AGN) detected in the hard X-rays (14-195 keV) by the Burst Alert Telescope (BAT) on board Swift. This sample allows us…
Direct estimates of nitrogen abundance for Seyfert 2 nuclei
O. L. Dors, M. V. Cardaci, G. F. Hägele +10
We derive the nitrogen and oxygen abundances in the Narrow Line Regions (NLRs) of a sample of 38 local () Seyfert~2 nuclei. For that, we consider narrow optical emis…
