    • 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, ...
    • Gravity or turbulence? - III. Evidence of pure thermal Jeans fragmentation at similar to 0.1 pc scale 
      Palau, Aina; Ballesteros Paredes, Javier; Vázquez Semadeni, Enrique; Sánchez Monge, Álvaro; Estalella, Robert; Fall, S. Michael; Zapata, Luis A.; Camacho, Vianey; Gómez, Laura; Naranjo Romero, Raúl; Busquet, Gemma; Fontani, Francesco (Oxford University Press, 2015)
      We combine previously published interferometric and single-dish data of relatively nearby massive dense cores that are actively forming stars to test whether their 'fragmentation level' is controlled by turbulent or thermal ...
    • Modelling the spinning dust emission from LDN1780 
      Vidal, Matías; Dickinson, Clive; Harper, S. E.; Casassus Montero, Simón; Witt, A. N. (Oxford University Press, 2020)
      We study the anomalous microwave emission (AME) in the Lynds Dark Nebula (LDN) 1780 on two angular scales. With publicly available data at an angular resolution of 1 degrees, we studied the spectral energy distribution of ...
    • Planck intermediate results XV. A study of anomalous microwave emission in Galactic clouds (Corrigendum - ... 
      Ade, P. A. R.; Casassus Montero, Simón (EDP Sciences S A, 2018)
    • A protostellar jet emanating from a hypercompact H II region 
      Guzmán, Andrés E.; Garay Brignardello, Guido; Rodríguez, Luis F.; Contreras, Yanett; Dougados, Catherine; Cabrit, Sylvie (The American Astronomical Society, 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 ...
    • Resolved observations at 31 GHz of spinning dust emissivity variations in rho Oph 
      Arce Tord, Carla; Vidal, Matias; Casassus Montero, Simón; Cárcamo, Miguel; Dickinson, Clive; Hensley, Brandon S.; Génova Santos, Ricardo; Bond, J. Richard; Jones, Michael E.; Readhead, Anthony C. S.; Taylor, Ángela C.; Zensus, J. Anton (Oxford University Press, 2020)
      The rho Oph molecular cloud is one of the best examples of spinning dust emission, first detected by the cosmic background imager (CBI). Here, we present 4.5 arcmin observations with CBI 2 that confirm 31 GHz emission from ...
