Chemical abundances in Seyfert galaxies -- V. The discovery of shocked emission outside the AGN ionization axis

R. A. Riffel, O. L. Dors, M. Armah +9

We present maps for the electron temperature in the inner kpc of three luminous Seyfert galaxies: Mrk 79, Mrk 348, and Mrk 607 obtained from Gemini GMOS-IFU observations at spatial…

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…
