Chemical abundances of Seyfert 2 AGNs-III. Reducing the oxygen abundance discrepancy
O. L. Dors, R. Maiolino, M. V. Cardaci +4
We investigate the discrepancy between oxygen abundance estimations for narrow-line regions (NLRs) of Active Galactic Nuclei (AGNs) type Seyfert 2 derived by using direct estimatio…

Chemical abundances of Seyfert 2 AGNs II. N2 metallicity calibration based on SDSS
S. P. Carvalho, O. L. Dors, M. V. Cardaci +6
We present a semi-empirical calibration between the metallicity () of Seyfert 2 Active Galactic Nuclei and the =log([N II]6584/H) emission-line intensity ratio. This c…

Chemical abundances of Seyfert 2 AGNs I. Comparing oxygen abundances from distinct methods using SDSS
O. L. Dors, P. Freitas-Lemes, E. B. Amores +6
We compare the oxygen abundance (O/H) of the Narrow Line Regions (NLRs) of Seyfert 2 AGNs obtained through strong-line methods and from direct measurements of the electron temperat…
