• Lyman α wing absorption in cool white dwarf stars 

      Rohrmann, R. D.; Althaus, Leandro Gabriel; Kepler, Souza Oliveira (2011) [Artículo de periódico]
      Kowalski & Saumon identified the missing absorption mechanism in the observed spectra of cool white dwarf stars as the Lyman α red wing formed by the collisions between atomic and molecular hydrogen and successfully explained ...
    • Molecular hydrogen and [Fe II] in active galactic nuclei 

      Rodriguez-Ardila, Alberto; Pastoriza, Miriani Griselda; Viegas, Sueli Maria Marino; Sigut, T.A.A.; Pradhan, Anil K. (2004) [Artículo de periódico]
      Near-infrared spectroscopy is used to study the kinematics and excitation mechanisms of H2 and [Fe II] lines in a sample of mostly Seyfert 1 galaxies. The spectral coverage allows simultaneous observation of the JHK bands, ...
    • Molecular hydrogen and [Fe II] in active galactic nuclei – III. Low-ionization nuclear emission-line region and star-forming galaxies 

      Riffel, Rogério; Rodriguez-Ardila, Alberto; Aleman, Isabel Regina Guerra; Brotherton, Mike; Pastoriza, Miriani Griselda; Bonatto, Charles Jose; Dors Júnior, Oli Luiz (2013) [Artículo de periódico]
      We study the kinematics and excitation mechanisms of H2 and [Fe II] lines in a sample of 67 emission-line galaxies with Infrared Telescope Facility SpeX near-infrared (0.8–2.4 μm) spectroscopy together with new photoionization ...
    • Molecular hydrogen and [Fe II] in active galactic nuclei – II. Results for Seyfert 2 galaxies 

      Rodriguez-Ardila, Alberto; Riffel, Rogério; Pastoriza, Miriani Griselda (2005) [Artículo de periódico]
      Near-infrared spectroscopy is used to study the kinematics and excitation mechanisms of H2 and [Fe II] lines in a sample dominated by Seyfert 2 galaxies. The spectra simultaneously cover the JHK bands, allowing us to compare ...
    • The influence of vibration-rotation interaction on band intensity parameters for ZrO and CuH 

      Gallas, Jason Alfredo Carlson; Francke Sandoval, Ricardo Eugenio; Grieneisen, Hans Peter Henrik; Chakraborty, Bijoy P. (1979) [Artículo de periódico]
      Effects of vibration-rotation interaction have been studied on the band intensity parameters of ZrO and CuH molecules. Band strengths have been calculated for the ZrO α(C³3Δ-X' 3Δ) band system, and, in the absence of an ...
