Chemical abundances of Seyfert 2 AGNs, II: N2 metallicity calibration based on SDSS
(Wiley Blackwell Publishing, Inc, 2020-06)
We present a semi-empirical calibration between the metallicity (Z) of Seyfert 2 active galactic nuclei and the N2 = log([N II]λ6584/H a) emission-line intensity ratio. This calibration was derived through the [OIII]λ5007/[O ...
