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…
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…
Gemini NIFS survey of feeding and feedback in nearby Active Galaxies -- IV. Excitation
Rogemar A. Riffel, Marina Bianchin, Rogerio Riffel +5
The near-infrared spectra of Active Galactic Nuclei (AGN) present emission lines of different atomic and molecular species. The mechanisms involved in the origin of these emission…
A panchromatic spatially resolved study of the inner 500pc of NGC1052 -- II: Gas excitation and kinematics
Luis G. Dahmer-Hahn, Rogério Riffel, Tiago V. Ricci +8
We map the optical and near-infrared (NIR) emission-line flux distributions and kinematics of the inner 320535pc of the elliptical galaxy NGC1052. The integral field sp…
Outflows, Inflows and Young Stars in the inner 200 pc of the Seyfert galaxy NGC 2110
Marlon R. Diniz, Rogemar A. Riffel, Thaisa Storchi-Bergmann +1
We present a two-dimensional mapping of stellar population age components, emission-line fluxes, gas excitation and kinematics within the inner pc of the Seyfert 2 galaxy…
A close look at the dwarf AGN of NGC 4395: optical and near-IR integral field spectroscopy
Carine Brum, Marlon R. Diniz, Rogemar A. Riffel +7
Intermediate mass black holes (10-10 M) in the center of dwarf galaxies are believed to be analogous to growing Active Galactic Nuclei (AGN) in the early Universe.…
Gemini NIFS survey of feeding and feedback in nearbyActive Galaxies - III. Ionized versus warm molecular gasmasses and distributions
Astor J. Schonell, Thaisa Storchi-Bergmann, Rogemar A. Riffel +5
We have used the Gemini Near-Infrared Integral Field Spectrograph (NIFS) in the J and K bands to map the distribution, excitation and kinematics of the ionized HII and warm molecul…
A panchromatic spatially resolved study of the inner 500 pc of NGC 1052 - I: Stellar population
Luis Gabriel Dahmer-Hahn, Rogério Riffel, João Evangelista Steiner +6
We map optical and near-infrared (NIR) stellar population properties of the inner 320535pc of the elliptical galaxy NGC1052. The optical and NIR spectra were obtained u…
Gemini NIFS survey of feeding and feedback processes in nearby Active Galaxies: II -The sample and surface mass density profiles
R. A. Riffel, T. Storchi-Bergmann, R. Riffel +10
We present and characterize a sample of 20 nearby Seyfert galaxies selected for having BAT 14--195keV luminosities erg s, redshift 0.015, being acc…
Gemini NIFS survey of feeding and feedback processes in nearby Active Galaxies: I - Stellar kinematics
Rogemar A. Riffel, Thaisa Storchi-Bergmann, Rogerio Riffel +4
We use the Gemini Near-Infrared Integral Field Spectrograph (NIFS) to map the stellar kinematics of the inner few hundred parsecs of a sample of 16 nearby Seyfert galaxies, at a sp…
Disentangling the near infrared continuum spectral components of the inner 500 pc of Mrk 573: two-dimensional maps
