    • A Protostellar Jet Emanating from a hypercompact H II Region 
      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 ...
    • ALMA observations of two massive and dense MALT90 clumps 
      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 ...
    • Eeffect of feedback of massive stars in the fragmentation, distribution, and kinematics of the gas in two ... 
      Rebolledo, David; Guzmán, Andrés; Contreras, Yanett; Garay Brignardello, Guido; Medina, S. N. X.; Sanhueza, Patricio; Green, Anne; Castro, Camila; Guzmán, Viviana; Burton, Michael G. (IOP, 2020)
      We present ALMA high spatial resolution observations toward two star-forming regions located in one of the most extreme zones of star formation in the Galaxy, the Carina Nebula. One region is located at the center of the ...
    • Infall signatures in a prestellar core embedded in the high-mass 70 mu m Dark IRDC G331.372-00.116 
      Contreras, Yanett; Sanhueza, Patricio; Jackson, James M.; Guzmán, Andrés E.; Longmore, Steven; Garay Brignardello, Guido; Zhang, Qizhou; Quang, Nguyen-Lu'o'Ng; Tatematsu, Ken'ichi; Nakamura, Fumitaka; Sakai, Takeshi; Ohashi, Satoshi; Liu, Tie; Saito, Masao; Gómez, Laura; Rathborne, Jill; Whitaker, Scott (IOP Publishing, 2018-07)
      Using Galactic Plane surveys, we have selected a massive (1200M circle dot), cold (14 K) 3.6-70 mu m dark IRDC, G331.372-00.116. This infrared dark cloud (IRDC) has the potential to form high-mass stars, and given the ...
    • Linking dense gas from the milky way to external galaxies 
      Stephens, Ian W.; Jackson, James M.; Whitaker, J. Scott; Contreras, Yanett; Guzmán, Andres E.; Sanhueza, Patricio; Foster, Jonathan B.; Rathborne, Jill (IOP Publishing, 2016-06-10)
      In a survey of 65 galaxies, Gao & Solomon found a tight linear relation between the infrared luminosity (L-IR, a proxy for the star formation rate) and the HCN(1-0) luminosity (L-HCN). Wu et al. found that this relation ...
    • SuperMALT: Physical and Chemical Properties of Massive and Dense Clumps 
      Neupane, Sudeep; Garay Brignardello, Guido; Contreras, Yanett (Cambridge University Press, 2017)
      The SuperMALT survey is observing 76 MALT90 clumps at different evolutionary stages (from pre-stellar or quiescent to HII) in high excitation molecular lines and key isotopomers using the Apex 12m telescope with an angular ...
    • The carina nebula and gum 31 molecular complex: II. The distribution of the atomic gas revealed in unprecedented ... 
      Rebolledo, David; Green, Anne J.; Burton, Michael; Brooks, Kate J.; Breen, Shari L.; Gaensler, B. M.; Contreras, Yanett; Braiding, Catherine; Purcell, Cormac (Oxford University Press, 2017)
      We report high spatial resolution observations of the HI 21cm line in the Carina Nebula and the Gum 31 region obtained with the Australia Telescope Compact Array. The observations covered similar to 12 deg(2) centred on l ...
