    • Hubble Space Telescope faint object camera spectroscopy of the narrow-line region of NGC 4151. I. Gas kinematics 

      Winge, Claudia; Axon, David J.; Macchetto, Ferdinando Duccio; Capetti, A.; Marconi, A. (1999) [Artigo de periódico]
      We present the results from a detailed kinematic analysis of both ground-based, and Hubble Space Telescope (HST )/Faint Object Camera long-slit spectroscopy at subarcsecond spatial resolution of the narrow-line region (NLR) ...

    • A photometric and kinematic study of the stars and interstellar medium in the central 2 kiloparsecs of NGC 3379 

      Pastoriza, Miriani Griselda; Winge, Claudia; Ferrari, Fabricio; Macchetto, Ferdinando Duccio; Caon, Nicola (2000) [Artigo de periódico]
      Hubble Space Telescope images of NGC 3379 show that the V and I luminosity profiles in the inner 13" of this E1 galaxy are represented by two di†erent components : a stellar bulge following a Sérsic law with exponent n=2.36 ...

    • A survey of the interstellar medium in early-type galaxies. III. Stellar and gas kinematics 

      Caon, Nicola; Macchetto, Ferdinando Duccio; Pastoriza, Miriani Griselda (2000) [Artigo de periódico]
      We present gaseous and stellar kinematics for 14 gas-rich early-type galaxies. Half of the sample exhibit irregular gaseous velocity profiles ; gas/star counter-rotation is visible in Ðve galaxies. We also find five ...

    • Survey of the ISM in early-type galaxies 

      Ferrari, Fabricio; Pastoriza, Miriani Griselda; Macchetto, Ferdinando Duccio; Bonatto, Charles Jose; Panagia, Nino; Sparks, William B. (2002) [Artigo de periódico]
      We present mid-IR photometric properties for a sample of 28 early-type galaxies observed at 6.75, 9.63 and 15 m with the ISOCAM instrument on board the ISO satellite. We nd total mid-IR luminosities in the range (3−42) x ...

    • The origin of the narrow-line region of Markarian 3 : an overpressured jet cocoon 

      Capetti, A.; Axon, David J.; Macchetto, Ferdinando Duccio; Marconi, A.; Winge, Claudia (1999) [Artigo de periódico]
      We have obtained Hubble Space Telescope (HST ) Faint Object Camera (FOC) f/48 long-slit optical spectroscopy of the inner 2" of the narrow-line region (NLR) of the Seyfert 2 galaxy Mrk 3 with a spatial resolution of 0".06. ...
