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 ($Z$) of Seyfert 2 Active Galactic Nuclei and the $N2$=log([N II]$\lambda$6584/H$\alpha$) emission-line intensity ratio. This c…
