    • An emission mechanism for extragalactic radio jets 

      Yoon, Peter H.; Ziebell, Luiz Fernando (1996) [Artigo de periódico]
      The observed emtsswns of radio waves from extragalactic radio jets are customarily interpreted in terms of the incoherent synchrotron radiation produced by a nonthermal population of relativistic electrons (or positrons) ...

    • An Hα nuclear spiral structure in the E0 active galaxy Arp 102B 

      Fathi, Kambiz; Axon, David J.; Storchi-Bergmann, Thaisa; Kharb, Preeti; Robinson, Andrew; Marconi, A.; Maciejewski, Witold B.; Capetti, A. (2011) [Artigo de periódico]
      We report the discovery of a two-armed mini-spiral structure within the inner kiloparsec of the E0 LINER/Seyfert 1 galaxy Arp 102B. The arms are observed in Hα emission and located east and west of the nucleus, extending ...

    • An outflow perpendicular to the radio jet in the Seyfert nucleus of NGC 5929 

      Riffel, Rogemar André; Storchi-Bergmann, Thaisa; Riffel, Rogério (2013) [Artigo de periódico]
      We report the observation of an outflow perpendicular to the radio jet in near-infrared integral field spectra of the inner 250 pc of the Seyfert 2 galaxy NGC 5929. The observations were obtained with the Gemini Near-infrared ...

    • Nuclear spirals as feeding channels to the supermassive black hole : the case of the galaxy NGC 6951 

      Storchi-Bergmann, Thaisa; Dors Júnior, Oli Luiz; Riffel, Rogemar André (2007) [Artigo de periódico]
      We report the discovery of gas streaming motions along nuclear spiral arms toward the LINER nucleus of the galaxyNGC 6951. The observations, obtained using theGMOS integral field spectrograph on the Gemini North telescope, ...
