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…
Gemini NIFS survey of feeding and feedback processes in nearby Active Galaxies: VI -- Stellar Populations
Rogério Riffel, Luis G. Dahmer-Hahn, Rogemar A. Riffel +8
We use Gemini Near-Infrared Integral Field Spectrograph (NIFS) adaptive optics assisted data-cubes to map the stellar population of the inner few hundred parsecs of a sample of 18…
Optical Properties of Peaked Spectrum Radio Sources
R. S. Nascimento, A. Rodríguez-Ardila, L. Dahmer-Hahn +5
In this work, we study the optical properties of compact radio sources selected from the literature in order to determine the impact of the radio-jet in their circumnuclear environ…
A Gemini-NIFS view of the merger remnant NGC 34
J. C. Motter, R. Riffel, T. V. Ricci +8
The merger remnant NGC 34 is a local luminous infrared galaxy (LIRG) hosting a nuclear starburst and a hard X-ray source associated with a putative, obscured Seyfert~2 nucleus. In…
