    • Guzmán Fernández, Andrés; Garay Brignardello, Guido; Rodríguez, Luis F.; Contreras, Yanett; Dougados, Catherine; Cabrit, Sylvie (IOP, 2016)
      We present radio continuum observations of the high-mass young stellar object (HMYSO) G345.4938+01.4677 obtained using the Australia Telescope Compact Array (ATCA) at 5, 9, 17, and 19 GHz. These observations provide definite ...

      j\3.4 mm toward the Cepheus A East star-forming region. The HCO` line shows emission up to velocities of D50 km s~1 relative to the ambient cloud velocity. The spatial distribution of the highvelocity gas is bipolar, ...
    • Garay Brignardello, Guido; Mardones Pérez, Diego; Rodríguez, Luis F.; Caselli, Paola; Bourke, Tyler L. (2002-03-10)
      We report Swedish-ESO Submillimetre Telescope observations of seven bipolar outÑows thought to be associated with Class 0 objects in the t\0 J\3]2 and J\2]1 transitions of SiO and Jk\ 3k and transitions of Methanol and ...
    • Franco Hernández, Ramiro; Moran, James M.; Rodríguez, Luis F.; Garay Brignardello, Guido (2009-08-20)
      We present Very Large Array 1.3 cm radio continuum and water maser observations as well as Submillimeter Array SO2 (226.300 GHz) and 1.3 mm dust continuum observations toward the massive star formation region IRAS ...
