Empirical calibration for helium abundance determinations in Active Galactic Nuclei
O. L. Dors, G. C. Almeida, C. B. Oliveira +10
For the first time, a calibration between the HeI /H emission line ratio and the helium abundance =12+log(He/H) for Narrow line regions (NLRs) of Seyfert~2 Activ…
Chemical abundances of LINER galaxies -- Nitrogen abundance estimations
C. B. Oliveira, A. C. Krabbe, O. L. Dors +5
In this work, we investigated the nitrogen and oxygen abundances in a sample of galaxies with Low Ionization Nuclear Emission Regions (LINERs) in their nucleus. Optical spectroscop…
The extent and power of "maintainance mode" feedback in MaNGA AGN
Lara Gatto, T. Storchi-Bergmann, Rogemar A. Riffel +5
We study the ionised gas kinematics of 293 Active Galactic Nuclei (AGN) hosts as compared to that of 485 control galaxies from the MaNGA-SDSS survey using measurements of the [OIII…
Mapping the stellar population and gas excitation of MaNGA galaxies with MEGACUBES. Results for AGN versus control sample
Rogério Riffel, Nicolas D. Mallmann, Sandro B. Rembold +11
We present spaxel-by-spaxel stellar population fits for the 10 thousand MaNGA datacubes. We provide multiple extension fits files, nominated as MEGACUBES, with maps of severa…
Active Galactic Nuclei signatures in Red Geyser galaxies from Gemini GMOS-IFU observations
G. S. Ilha, R. A. Riffel, T. V. Ricci +8
Red Geysers are quiescent galaxies with galactic scale ionised outflows, likely due to low-luminosity Active Galactic Nuclei (AGN). We used Gemini GMOS-IFU observations of the inne…
