New quantitative nitrogen abundance estimations in a sample of Seyfert 2 Active Galactic Nuclei
O. L. Dors, K. Z. Arellano-Cordova, M. V. Cardaci +1
We obtained new quantitative determinations of the nitrogen abundance and a consistent relation between nitrogen and oxygen abundances for a sample of Seyfert 2 galaxies located at…
Interaction effects on galaxy pairs with GeminiGMOS-III: Stellar population synthesis
A. C. Krabbe, D. A. Rosa, M. G. Pastoriza +4
We present an observational study of the impacts of the interactions on the stellar population in a sample of galaxy pairs. Long-slit spectra in the wavelength range 3440-7300 Å ob…
New metallicity calibration for Seyfert 2 galaxies based on the N2O2 index
C. S. Castro, O. L. Dors, M. V. Cardaci +1
We derive a new relation between the metallicity of Seyfert 2 Active Galactic Nuclei (AGNs) and the intensity of the narrow emission-lines ratio =log([N II]6584/[O II]3…
