Diagnostic diagrams for ram-pressure stripped candidates
A. C. Krabbe, J. A. Hernandez-Jimenez, C. Mendes de Oliveira +7
This paper presents a method for finding ram-pressure stripped (RPS) galaxy candidates by performing a morphological analysis of galaxy images obtained from the Legacy survey. We c…
Cosmic metallicity evolution of Active Galactic Nuclei: Implications for optical diagnostic diagrams
Oli L. Dors, M. V. Cardaci, G. F. Hagele +5
We analyze the validity of optical diagnostic diagrams relying on emission-lines ratios and in the context of classifying Active Galactic Nuclei (AGNs) according to the cosmic meta…
AGN feedback and star formation in the peculiar galaxy NGC 232: Insights from VLT-MUSE Observations
Jose Henrique Costa-Souza, Rogemar A. Riffel, Oli L. Dors +2
We use VLT-MUSE integral field unit data to study the ionized gas physical properties and kinematics as well as the stellar populations of the Seyfert 2 galaxy NGC\,232 as an oppor…
Evidence for low power radio jet-ISM interaction at 10 parsec in the dwarf AGN host NGC 4395
Payel Nandi, C. S. Stalin, D. J. Saikia +10
Black hole driven outflows in galaxies hosting active galactic nuclei (AGN) may interact with their interstellar medium (ISM) affecting star formation. Such feedback processes, rem…
Chemical abundances in Seyfert galaxies X. Sulphur abundance estimates
O. L. Dors, M. Valerdi, R. A. Riffel +12
For the first time, the sulphur abundance relative to hydrogen (S/H) in the Narrow Line Regions of a sample of Seyfert 2 nuclei (Sy 2s) has been derived via direct estimation of th…
Oxygen abundances in the narrow line regions of Seyfert galaxies and the metallicity-luminosity relation
Mark Armah, Rogério Riffel, O. L. Dors +7
We present oxygen abundances relative to hydrogen (O/H) in the narrow line regions (NLRs) gas phases of Seyferts 1 (Sy 1s) and Seyferts 2 (Sy 2s) Active Galactic Nuclei (AGNs). We…
