Blowing star formation away in AGN Hosts (BAH) -- II. Investigating the origin of the H2 emission excess in nearby galaxies with JWST MIRI
Rogemar A. Riffel, Gabriel L. Souza-Oliveira, José Henrique Costa-Souza +4
We use James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) medium-resolution spectrometer (MRS) observations of 3C 293 (UGC 8782), CGCG 012-070 and NGC 3884 to investi…
Spatially-resolved gas-phase metallicity in Seyfert galaxies
Mark Armah, Rogério Riffel, L. G. Dahmer-Hahn +7
We explore the relations between the gas-phase metallicity radial profiles (few hundred inner parsec) and multiple galaxy properties for 15 Seyfert galaxies from the AGNIFS (Active…
Digging deeper into NGC 6868 II: ionized gas and excitation mechanism
João P. V. Benedetti, Rogério Riffel, Tiago Ricci +9
We studied the ionized gas in the inner region ( pc) of the galaxy NGC 6868 using Gemini/GMOS integral field unit observations. Channel maps reveal complex ki…
Spatially resolved spectroscopic observations of gas emission in dwarf galaxies hosting accreting black hole candidate
Kelly F. Heckler, Rogemar A. Riffel, Tiago V. Ricci
Recent studies on dwarf galaxies reveal that some of them harbor a massive black hole (BH), which is believed to have a similar mass of the Supermassive BH "seeds" at early times.…
Observational constraints on the stellar recycled gas in active galactic nuclei feeding
Rogerio Riffel, Luis G. Dahmer-Hahn, Alexandre Vazdekis +15
Near-infrared long-slit spectroscopy has been used to study the stellar population (SP) of the low luminosity active galactic nuclei (AGN) and matched analogues (LLAMA) sample. To…
SMARTY: The mileS Moderate resolution neAr-infRared sTellar librarY
Michele Bertoldo-Coêlho, Rogério Riffel, Marina Trevisan +13
Most of the observed galaxies cannot be resolved into individual stars and are studied through their integrated spectrum using simple stellar populations (SSPs) models, with stella…
