AGN driven outflows in the OH absorber galaxy IRAS 19154+2704
C. Hekatelyne, Thaisa Storchi-Bergmann, Rogemar A. Riffel +4
We present a two-dimensional study of the gas distribution, excitation and kinematics of the OH absorber galaxy IRAS 19154+2704 using Gemini GMOS-IFU observations. Its continuum im…
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…
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…
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…
A Decade of Near-Infrared Variability in NGC4388: Insights into the AGN Structure
Luis G. Dahmer-Hahn, Alberto Rodríguez-Ardila, Marina Bianchin +4
Variability studies have proven to be a powerful diagnostic tool for understanding the physics and properties of of Active Galactic Nuclei (AGNs). They provide insights into the sp…
Digging deeper into NGC\,6868 I: stellar population
João P. V. Benedetti, Rogério Riffel, Tiago Ricci +8
We use Gemini integral field unit observations to map the stellar population properties in the inner region ( pc) of the galaxy NGC 6868. In order to understa…
Cold molecular gas outflow encasing the ionised one in the Seyfert galaxy NGC 3281
Bruno Dall'Agnol de Oliveira, Thaisa Storchi-Bergmann, Raffaella Morganti +2
We present ALMA CO(2-1) observations of the Seyfert 2 galaxy NGC 3281 at 100 pc spatial resolution. This galaxy was previously known to present a bi-conical ionised gas outf…
The AGNIFS survey: spatially resolved observations of hot molecular and ionised outflows in nearby active galaxies
R. A. Riffel, T. Storchi-Bergmann, R. Riffel +17
We present the hot molecular and warm ionised gas kinematics for 33 nearby () X-ray selected active galaxies using the Hm and Br emiss…
Spatially resolved observations of outflows in the radio loud AGN of UGC 8782
Rogemar A. Riffel, Rogério Riffel, Marina Bianchin +3
We use optical Integral Field Spectroscopy (IFU) to study the gas emission structure and kinematics in the inner 3.44.9 kpc region of the galaxy UGC 8782 (3C 293), host…
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…
A Catalog of 71 Coronal Line Galaxies in MaNGA: [NeV] is an Effective AGN Tracer
James Negus, Julia M. Comerford, Francisco Muller Sanchez +5
Despite the importance of AGN in galaxy evolution, accurate AGN identification is often challenging, as common AGN diagnostics can be confused by contributions from star formation…
