    • A massive prestellar clump hosting no high-mass cores 
      Sanhueza, Patricio; Jackson, James; Zhang, Qizhou; Guzmán Fernández, Andrés; Lu, Xing; Stephens, Ian W.; Wang, Ke; Tatematsu, Ken'ichi (IOP Publishing, 2017-06-01)
      The infrared dark cloud (IRDC) G028.23-00.19 hosts a massive (1500M(circle dot)), cold (12 K), and 3.6-70 mu m IR dark clump (MM1) that has the potential to form high-mass stars. We observed this prestellar clump candidate ...
    • A Megacam Survey of Outer Halo Satellites. VI. The Spatially resolved Starformation History of the Carina ... 
      Santana Rojas, Felipe; Muñoz Vidal, Ricardo Rodrigo; de Boer, T. J. L.; Simon, Joshua D.; Geha, Marla; Coté, Patrick; Guzmán Fernández, Andrés; Stetson, Peter B.; Djorgovski, S. George (IOP, 2016)
      We present the spatially resolved star-formation history (SFH) of the Carina dwarf spheroidal galaxy, obtained from deep, wide-field g and r imaging and a metallicity distribution from the literature. Our photometry covers ...
    • 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 ...
    • A search for ionized jets towards massive young stellar objects 
      Purser, S. J. D.; Lumsden, S. L.; Hoare, M. G.; Urquhart, J. S.; Cunningham, N.; Purcell, C. R.; Brooks, K. J.; Garay Brignardello, Guido; Guzmán Fernández, Andrés; Voronkov, M. A. (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, ...
    • Molecular Line Emission Towards High-Mass Clumps: The MALT90 Catalogue 
      Rathborne, Jill; Whitaker, John; Jackson, J. M.; Foster, J. B.; Contreras, Y.; Stephens, I. W.; Guzmán Fernández, Andrés; Longmore, S. N.; Sanhueza, P.; Schuller, F.; Wyrowski, Friedrich; Urquhart, J. S. (Cambridge University Press, 2016)
      The Millimetre Astronomy Legacy Team 90 GHz survey aims to characterise the physical and chemical evolution of high-mass clumps. Recently completed, it mapped 90 GHz line emission towards 3 246 high-mass clumps identified ...
