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 IV. Composite models calculated by photoionization + shocks
O. L. Dors, M. Contini, R. A. Riffel +4
We build detailed composite models of photoionization and shock ionization based on the SUMA code to reproduce emission lines emitted from the Narrow Line Regions (NLR) of Seyfert…
Modeling Dark Matter Halos with Nonlinear Field Theories
R. A. C. Correa, P. H. R. S. Moraes, A. de Souza Dutra +3
In the present work, we adopt a nonlinear scalar field theory coupled to the gravity sector to model galactic dark matter. We found analytical solutions for the scalar field couple…
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…
A new tool to derive chemical abundances in Type-2 Active Galactic Nuclei
R. García-Benito, E. Pérez-Montero, O. L. Dors +3
We present a new tool for the analysis of the optical emission lines of the gas in the Narrow Line Region (NLR) around Active Galactic Nuclei (AGNs). This new tool can be used in l…
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…
