      We present Very Long Baseline Array proper-motion measurements of water masers toward two young stellar objects (YSOs) of the W75 N star-forming region. We find that these two objects are remarkable for having a similar ...

      The physical and chemical properties of prestellar cores, especially massive ones, are still far from being well understood due to the lack of a large sample. The low dust temperature (< 14 K) of Planck cold clumps makes ...
    • Guevara Navea, Cristian Felipe (Universidad de Chile, 2011)
      El objetivo de esta tesis fue la de caracterizar las propiedades físicas de zonas de formación de estrellas masivas en nubes moleculares y que se encuentran localizadas en la Galaxia externa austral; y realizar una ...

      We report molecular line and dust continuum observations, made with the Swedish-ESO Submillimeter Telescope, toward four young high-mass star-forming regions associated with highly luminous (L > 6 × 105 L ) Infrared Astronomical ...

      We present sensitive near-infrared (J, H, and K) imaging observations toward four luminous massive star-forming regions in the Norma Spiral Arm: G324.201+0.119, G328.307+0.432, G329.337+0.147, and G330.949−0.174. We ...
    • Contreras, Yanett; Garay Brignardello, Guido; Rathborne, Jill; Sanhueza, Patricio (OXFORD UNIV PRESS, 2016)
      Recent surveys of dust continuum emission at sub-mm wavelengths have shown that filamentary molecular clouds are ubiquitous along the Galactic plane. These structures are inhomogeneous, with overdensities that are sometimes ...
    • Garay Brignardello, Guido; Mardones Pérez, Diego; Contreras Morales, Yanett Alejandra; Pineda, Jaime; Servajean Bergoeing, Elise; Guzmán Fernández, Andrés (The American Astronomical Society, 2015-01-20)
      We report molecular line observations, made with ASTE and SEST, and dust continuum observations at 0.87 mm, made with APEX, toward the cold dust core G305.136+0.068. The molecular observations show that the core is isolated ...

      Context. Ring-like structures in the interstellar medium (ISM) are commonly associated with high-mass stars. Kinematic studies of large structures in giant molecular clouds (GMCs) toward these ring-like structures may help ...

      We report observations of 6 cm, 3.6 cm, 1.3 cm, and 7 mm radio continuum, conducted with the Very Large Array, toward IRAS 18566+0408, one of the few sources known to harbor H(2)CO6 cm maser emission. Our observations ...
