    • First detection of the 448 GHz H2O transition in space 

      Pereira-Santaella, Miguel; González-Alfonso, Eduardo; Usero, Antonio; Garcia-Burillo, Santiago; Martín-Pintado, Jesús M.; Colina, Luis; Alonso-Herrero, Almudena; Arribas, Santiago; Cazzoli, Sara; Rico Villas, Fernando; Rigopoulou, Dimitra; Storchi-Bergmann, Thaisa (2017) [Artigo de periódico]
      We present the first detection of the ortho-H2O 423􀀀330 transition at 448 GHz in space. We observed this transition in the local (z = 0:010) luminous infrared (IR) galaxy ESO 320-G030 (IRAS F11506-3851) using the Atacama ...

    • High spatial resolution of the mid-infrared emission of the Compton-thick type 2 Seyfert galaxy, Markarian 3 

      Sales, Dinalva Aires de; Dutra, Daniel Ruschel; Pastoriza, Miriani Griselda; Riffel, Rogério; Winge, Claudia (2014) [Artigo de periódico]
      The mid-infrared (MIR) spectra observed with Gemini/Michelle have been used to study the nuclear region of the Compton-thick type 2 Seyfert galaxy, Markarian 3 (Mrk 3), at a spatial resolution of ∼200 pc. No polycyclic ...

    • LLAMA : normal star formation efficiencies of molecular gas in the centres of luminous Seyfert galaxies 

      Rosario, David; Riffel, Rogério; Müller, Allan Schnorr; Storchi-Bergmann, Thaisa; Veilleux, Sylvain (2018) [Artigo de periódico]
      Using new Atacama Pathfinder Experiment and James Clerk Maxwell Telescope spectroscopy of the CO 2→1 line, we undertake a controlled study of cold molecular gas in moderately luminous (Lbol = 1043–44.5 erg s−1) active ...

    • Polycyclic aromatic hydrocarbon and emission line ratios in active galactic nuclei and starburst galaxies 

      Sales, Dinalva Aires de; Pastoriza, Miriani Griselda; Riffel, Rogério (2010) [Artigo de periódico]
      We study the polycyclic aromatic hydrocarbon (PAH) bands, ionic emission lines, and mid-infrared continuum properties in a sample of 171 emission line galaxies taken from the literature plus 15 new active galactic nucleus ...

    • Polycyclic aromatic hydrocarbon in the central region of the Seyfert 2 galaxy NGC 1808 

      Sales, Dinalva Aires de; Pastoriza, Miriani Griselda; Riffel, Rogério; Winge, Claudia (2013) [Artigo de periódico]
      We present mid-infrared spectra of the Seyfert 2 galaxy NGC 1808, obtained with the Gemini’s Thermal-Region Camera Spectrograph at a spatial resolution of ∼26 pc. The high spatial resolution allowed us to detect bright ...
