A SINFONI view of the nuclear activity and circumnuclear star formation in NGC 4303 - II: Spatially resolved stellar populations
Natacha Z. Dametto, Rogério Riffel, Luis Colina +11
We present a spatially resolved stellar population study of the inner 200\,pc radius of NGC4303 based on near-infrared integral field spectroscopy with SINFONI/VLT at a spati…
Destruction and multiple ionization of PAHs by X-rays in circumnuclear regions of AGNs
Thiago Monfredini, Heidy M. Quitián-Lara, Felipe Fantuzzi +6
The infrared signatures of polycyclic aromatic hydrocarbons (PAHs) are observed in a variety of astrophysical objects, including the circumnuclear medium of active galactic nuclei…
Probing Evolutionary Population Synthesis Models in the Near Infrared with Early Type Galaxies
Luis Gabriel Dahmer-Hahn, Rogério Riffel, Alberto Rodríguez-Ardila +5
We performed a near-infrared (NIR, 1.0m-2.4m) stellar population study in a sample of early type galaxies. The synthesis was performed using five different evolutionary…
Star formation in AGNs at the hundred parsec scale using MIR high resolution images
Daniel Ruschel-Dutra, José Miguel Rodríguez Espinosa, Omaira González Martín +2
It has been well established in the past decades that the central black hole masses of galaxies correlate with dynamical properties of their harbouring bulges. This notion begs the…
Probing the Active Galactic Nuclei Unified Model Torus Properties in Seyfert Galaxies
Anelise Audibert, Rogério Riffel, Dinalva A. Sales +2
We studied the physical parameters of a sample comprising of all Spitzer/IRS public spectra of Seyfert galaxies in the mid-infrared (5.2-38m range) under the active galactic nuc…
A SINFONI view of the nuclear activity and circum-nuclear star formation in NGC 4303
Rogemar A. Riffel, L. Colina, T. Storchi-Bergmann +8
We present new maps of emission-line flux distributions and kinematics in both ionized (traced by HI and [FeII] lines) and molecular (H2) gas of the inner 0.7x0.7kpc2 of the galaxy…
