Powerful outflows of compact radio galaxies
Bárbara L. Miranda Marques, Alberto Rodríguez-Ardila, Marcos A. Fonseca-Faria +1
Gigahertz Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) sources are compact radio galaxies (RGs), with jets extending up to 20 kpc and ages <10^3 years. They are considere…
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…
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…
First detection of outflowing gas in the outskirts of the broad line region in 1H-0707-495
Alberto Rodriguez-Ardila, Marcos Antonio Fonseca-Faria, Denimara Dias dos Santos +2
We use near-infrared (NIR) spectroscopy covering simultaneously the bands to look for outflowing gas from the nuclear environment of 1H0707-495 taking advantage that this re…
