    • Probing the active galactic nucleus unified model torus properties in Seyfert galaxies 

      Audibert, Anelise; Riffel, Rogério; Sales, Dinalva Aires de; Pastoriza, Miriani Griselda; Dutra, Daniel Ruschel (2017) [Artigo de periódico]
      We studied the physical parameters of a sample comprising of all Spitzer/Infrared Spectrograph public spectra of Seyfert galaxies in the mid-infrared (5.2–38 μm range) under the active galactic nucleus (AGN) unified model. ...

    • The complex, dusty narrow-line region of NGC 4388 : gas–jet interactions, outflows and extinction revealed by near-IR spectroscopy 

      Rodrigues-Ardila, Alberto; Mason, Rachel E.; Martins, Lucimara Pires; Ramos Almeida, Cristina; Riffel, Rogemar André; Riffel, Rogério; Lira, Paulina; Gonzalez Martin, Omaira; Dametto, Natacha Zanon; Flohic, Helene; Ho, Luis C.; Dutra, Daniel Ruschel; Thanjavur, Karun; Colina, Luis; McDermid, Richard; Perlman, Eric; Winge, Claudia (2017) [Artigo de periódico]
      We present Gemini/GNIRS (Gemini Near-Infrared Spectrograph) spectroscopy of the Seyfert 2 galaxy NGC 4388, with simultaneous coverage from 0.85 to 2.5 μm. Several spatially extended emission lines are detected for the first ...
