    • Guzmán, Andres E.; Sanhueza, Patricio; Zapata, Luis; Garay Brignardello, Guido; Rodríguez, Luis Felipe (IOP, 2020)
      We present high spatial resolution (52 au) observations of the high-mass young stellar object (HMYSO) G345.4938+01.4677 made using the Atacama Large Millimeter/submillimeter Array. This O-type HMYSO is located at 2.38 kpc ...
    • Neupane, Sudeep; Garay Brignardello, Guido; Contreras, Yanett; Guzmán, Andrés; Rodríguez, Luis Felipe (IOP, 2020)
      We report Atacama Large Millimeter Array observations of 3 mm dust continuum emission and line emission, in HCO+, (HCO+)-C-13, N2H+, and CH3CN, toward two massive and dense clumps (MDCs) in early but distinct evolutionary ...

      We report studies of the relationships between the total bolometric luminosity (L-bol or L-TIR) and the molecular line luminosities of J = 1 - 0 transitions of (HCN)-C-13, (HCO+)-C-13, HCN, and HCO+ with data obtained from ...
    • Guzmán, Andrés; Guzmán, Viviana; Garay Brignardello, Guido; Bronfman Aguiló, Leonardo; Hechenleitner, Federico (Institute of Physics Publishing, 2018)
      We present molecular line observations of the high-mass molecular clump IRAS 16562−3959 taken at 3 mm using the Atacama Large Millimeter/submillimeter Array (ALMA) at 1. 007 angular resolution (0.014 pc spatial resolution). ...
    • Ginsburg, Adam; Garay Brignardello, Guido (IOP Publishing Ltd, 2018)
      We report ALMA observations with resolution approximate to 0 ''.5 at 3 mm of the extended Sgr B2 cloud in the Central Molecular Zone (CMZ). We detect 271 compact sources, most of which are smaller than 5000 au. By ruling ...
    • Reiter, Megan; Guzmán, Andrés E.; Haworth, Thomas J.; Klaassen, Pamela D.; McLeod, Anna F.; Garay Brignardello, Guido; Mottram, Joseph C. (Oxford University Press, 2020)
      We present new Atacama Large Millimeter/submillimeter Array observations of the tadpole, a small globule in the Carina Nebula that hosts the HH 900 jet+outflow system. Our data include (CO)-C-12, (CO)-C-13, (CO)-O-18 J=2-1, ...
    • Reiter, Megan; Haworth, Thomas J.; Guzmán, Andrés E.; Klaassen, Pamela D.; McLeod, Anna F.; Garay Brignardello, Guido (Oxford Univ Press, 2020)
      We combine Multi-Unit Spectroscopic Explorer and Atacama Large Millimeter/sub-millimeter Array observations with theoretical models to evaluate how a tadpole-shaped globule located in the Carina Nebula has been influenced ...
