    • Gemini NIFS survey of feeding and feedback in nearby active galaxies III. Ionized versus warm molecular gas masses and distributions 

      Schönell Júnior, Astor João; Storchi-Bergmann, Thaisa; Riffel, Rogemar André; Riffel, Rogério; Bianchin, Marina; Hahn, Luis Gabriel Dahmer; Diniz, Marlon Rodrigo; Dametto, Natacha Zanon (2019) [Journal article]
      We have used the Gemini Near-Infrared Integral Field Spectrograph in the J and K bands to map the distribution, excitation, and kinematics of the ionized H ii and warm molecular gas H2, in the inner few 100 pc of six nearby ...
    • Gemini NIFS survey of feeding and feedback processes in nearby active galaxies : II. The sample and surface mass density profilesthe hidden monster and its outflow 

      Riffel, Rogemar André; Storchi-Bergmann, Thaisa; Riffel, Rogério; Davies, Richard I.; Bianchin, Marina; Diniz, Marlon Rodrigo; Schönell Júnior, Astor João; Burtscher, Leonard; Crenshaw, Daniel Michael; Fischer, Travis C.; Hahn, Luis Gabriel Dahmer; Dametto, Natacha Zanon; Rosario, David (2018) [Journal article]
      We present and characterize a sample of 20 nearby Seyfert galaxies selected for having BAT 14–195 keV luminosities LX ≥ 1041.5 erg s−1, redshift z ≤ 0.015, being accessible for observations with the Gemini Near-Infrared ...
    • Gemini NIFS survey of feeding and feedback processes in nearby active galaxies : I. Stellar kinematics 

      Riffel, Rogemar André; Storchi-Bergmann, Thaisa; Riffel, Rogério; Hahn, Luis Gabriel Dahmer; Diniz, Marlon Rodrigo; Schönell Júnior, Astor João; Dametto, Natacha Zanon (2017) [Journal article]
      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 spatial resolution of tens of parsecs and ...
    • A panchromatic spatially resolved study of the inner 500 pc of NGC 1052 : II. Gas excitation and kinematics 

      Hahn, Luis Gabriel Dahmer; Riffel, Rogério; Ricci, Tiago Vecchi; Steiner, João Evangelista; Storchi-Bergmann, Thaisa; Riffel, Rogemar André; Menezes, Roberto Bertoldo; Dametto, Natacha Zanon; Diniz, Marlon Rodrigo; Motter, Juliana Cristina; Dutra, Daniel Ruschel (2019) [Journal article]
      We map the optical and near-infrared (NIR) emission-line flux distributions and kinematics of the inner 320×535 pc2of the elliptical galaxy NGC 1052. The integral field spectra were obtained with the Gemini Telescope using ...
    • A panchromatic spatially resolved study of the inner 500 pc of NGC 1052 : I. Stellar population 

      Hahn, Luis Gabriel Dahmer; Riffel, Rogério; Steiner, João Evangelista; Riffel, Rogemar André; Menezes, Roberto Bertoldo; Ricci, Tiago Vecchi; Dametto, Natacha Zanon; Storchi-Bergmann, Thaisa; Diniz, Marlon Rodrigo (2019) [Journal article]
      We map optical and near-infrared (NIR) stellar population properties of the inner 320 × 535 pc2 of the elliptical galaxy NGC 1052. The optical and NIR spectra were obtained using the Gemini Integral Field Units of the GMOS ...
    • Probing evolutionary population synthesis models in the near infrared with early-type galaxies 

      Hahn, Luis Gabriel Dahmer; Riffel, Rogério; Rodriguez-Ardila, Alberto; Martins, Lucimara Pires; Kehrig, Carolina; Heckman, Timothy M.; Pastoriza, Miriani Griselda; Dametto, Natacha Zanon (2018) [Journal article]
      We performed a near-infrared (NIR; ∼1.0 –2.4 μm) stellar population study in a sample of early-type galaxies. The synthesis was performed using five different evolutionary population synthesis libraries of models. Our main ...
    • A SINFONI view of the nuclear activity and circumnuclear star formation in NGC4303-II. Spatially resolved stellar populations 

      Dametto, Natacha Zanon; Riffel, Rogério; Colina, Luis; Riffel, Rogemar André; Piqueras López, Javier; Davies, Richard I.; Burtscher, Leonard; Menezes, Roberto Bertoldo; Arribas, Santiago; Pastoriza, Miriani Griselda; Labiano, Alvaro; Storchi-Bergmann, Thaisa; Hahn, Luis Gabriel Dahmer; Sales, Dinalva Aires de (2019) [Journal article]
      We present a spatially resolved stellar population study of the inner∼200 pc radius ofNGC 4303 based on near-infrared integral field spectroscopy with SINFONI/VLT at a spatial resolution of 40–80 pc and using the STARLIGHT ...
