    • Optical spectroscopy and narrow-band images of the variable Seyfert 1 galaxy NGC 3783 

      Winge, Claudia; Pastoriza, Miriani Griselda; Storchi-Bergmann, Thaisa; Lipari, Sebastian (1992) [Artigo de periódico]
      We present narrow-band images centered on [O III] λ5007, Hα, and adjacent continua of the Seyfert 1 galaxy NGC 3783. The continuum images evidence that the bar emission is mainly due to old stars. The [O III] λ5007 image ...

    • A snapshot of the continuous emission of the active galactic nucleus in ngc 3783 from gamma-ray to radio wavelengths 

      Alloin, Danielle Marie; Santos-Lleo, M.; Peterson, Bradley M.; Wamsteker, W.; Altieri, B.; Brinkmann, W.; Crenshaw, Daniel Michael; George, I.M.; Clavel, J.; Glass, I.S.; Johnson, W.N.; Kriss, Gerard A.; Malkan, M.A.; Polidan, R.S.; Reichert, G.A.; Rodriguez-Pascual, P.M.; Romanishin, W.; Starr, C.H.; Stirpe, Giovanna M.; Taylor, M.; Turner, T.J.; Vega, H.J. de; Winge, Claudia; Wood, D.O.S. (1995) [Artigo de periódico]
      With the aim of better understanding the physical processes that produce the continuous emission in active galactic nuclei (AGNs), a snapshot of the overall continuous energy distribution of NGC 3783, from γ-ray to radio ...

    • Steps foward determination of the size and structure of the broad-line region in active galactic nuclei. V. Variability of the ultraviolet continuum and emission lines of NGC 3783

(1994) [Artigo de periódico]
      We report on the results of intensive ultraviolet spectral monitoring of the Seyfert 1 galaxy NGC 3783. The nucleus of NGC 3783 was observed with the International Ultraviolet Explorer satellite on a regular basis for a ...

(1994) [Artigo de periódico]
      The Seyfert 1 galaxy NGC 3783 was intensely monitored in several bands between 1991 December and 1992 August. This paper presents the results from the ground-based observations in the optical and near-IR bands, which ...
