(2007)We present observations of 1.2 mm dust continuum emission made with the Swedish-ESO Submillimeter Telescope toward 18 luminous IRAS point sources, all with colors typical of compact H II regions and associated with CS(2 ...
-
(UNIV CHICAGO PRESS, 2003-09-10)IRAS 16547 - 4247 is the most luminous (6.2 x 10(4) L-.) embedded young stellar object known to harbor a thermal radio jet. We report the discovery using the Very Large Telescope Infrared Spectrometer and Array Camera of ...
-
(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 ...

(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 ...
-
(Oxford University Press, 2016)Radio continuum observations using the Australia telescope compact array at 5.5, 9.0, 17.0 and 22.8 GHz have detected free-free emission associated with 45 of 49 massive young stellar objects and H ii regions. Of these, ...
-
(2011)We present five epochs of VLBI water maser observations around the massive protostar Cepheus A HW2 with 0.4 mas (0.3 au) resolution. The main goal of these observations was to follow the evolution of the remarkable water ...
-
(Universidad de Chile, 2010)El objetivo de esta tesis es estudiar las propiedades físicas y cinemáticas en el interior de seis núcleos densos y masivos seleccionados en base a la forma de sus perfiles de la línea CS(2-1), que indican existencia de ...

ALMA cycle 1 observations of the hh46/47 molecular outflow: structure, entrainment, and core impact (The American Astronomical Society, 2016-12-01)We present Atacama Large Millimeter/sub-millimeter Array Cycle 1 observations of the HH 46/47 molecular outflow using combined 12 m array and Atacama Compact Array observations. The improved angular resolution and sensitivity ...
-
(Universidad de Chile, 2014)El flujo molecular, bipolar y masivo G331.512-0.103 es uno de los flujos más potentes y luminosos en nuestra Galaxia. Localizado a una distancia de ∼ 7.5 kpc, está localizado cerca de la tangente del brazo espiral de Norma. ...
-
(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 ...
-
(Oxford University Press, 2015)We present high angular resolution (similar to 0.3 arcsec) submillimeter continuum (0.85 mm) and line observations of the O-type protostar IRAS 16547-4247 carried out with the Atacama Large Millimeter/Submillimeter Array ...
-
(IOP Publishing Ltd, 2017)Stellar feedback from high-mass stars (e.g., H II regions) can strongly influence the surrounding interstellar medium and regulate star formation. Our new ALMA observations reveal sequential high-mass star formation taking ...
-
(IOP Publishing, 2015)Molecular outflows driven by protostellar cluster members likely impact their surroundings and contribute to turbulence, affecting subsequent star formation. The very young Serpens South cluster consists of a particularly ...
-
(Oxford University Press, 2020)The ATOMS, standing for ALMA Three-millimeter Observations of Massive Star-forming regions, survey has observed 146 active star-forming regions with ALMA band 3, aiming to systematically investigate the spatial distribution ...
-
(Oxford University Press, 2020)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 ...
-
(1991-02-10)The central 2 arcsec x 2 arcsec region of the SMC has been fully surveyed to search for (C-12)O emission in the J = 1-0 transition. (C-12)O emission from two large complexes located in the southwest and northeast regions ...
-
(Universidad de ChilePrograma Cybertesis, 2007)En esta tesis presento observaciones de la emisión en las líneas moleculares C8(2 -+ 1) y 13CO(2 -+ 1) hechas con el telescopio 8E8T, hacia las regiones de formación estelar NGC 6334 y NGC 6357. Observé un total de 68 ...
-
(UNIV CHICAGO PRESS, 2001-05-10)We present spectroscopic observations of object CE 315 revealing a blue continuum with strong emission lines. Most of the detected lines are identified with He I or He II in emission, with a handful of faint lines of ...
-
(UNIV CHICAGO PRESS, 1994-07-20)At angular resolution of approximately 1 arc second(s) the Cepheus A East Radio source is known to consist of 16 compact components clustered within a 25 arc second(s) radius region, most of which are aligned in stringlike ...
