• Kinematics of the central regions of NGC 1672 

      Díaz, Rubén Joaquín; Carranza, Gustavo Jose; Dottori, Horacio Alberto; Goldes, G. (1999) [Artigo de periódico]
      We present the detailed velocity field of the central 2 kpc of the LINER galaxy NGC 1672. The iso- velocity map shows a rotational pattern with a velocity gradient of 50 km s-ˡ arcsec-ˡ in the inner 6" (1"≈ 70 pc), indicating ...

(1997) [Artigo de periódico]
      The results of an optical monitoring campaign on the active nucleus in the luminous Seyfert 1 galaxy Fairall 9 are presented. This campaign was undertaken in parallel with ultraviolet spectroscopic monitoring with the IUE ...
