    • A cluster in the making: ALMA reveals the initial conditions for high-mass cluster formation 
      Rathborne, Jill; Longmore, S. N.; Jackson, J. M.; Alves, J. F.; Bally, J.; Bastian, N.; Contreras, Y.; Foster, J. B.; Garay Brignardello, Guido; Kruijssen, J. M.; Testi, L.; Walsh, A. J. (IOP PUBLISHING LTD, 2015)
      G0.253+0.016 is a molecular clump that appears to be on the verge of forming a high-mass cluster: its extremely low dust temperature, high mass, and high density, combined with its lack of prevalent star formation, make ...

C.; Bains, I.; Bontemps, S.; Bronfman Aguiló, Leonardo; Caswel, J.; Deharveng, L.; Ellingsen, S.; Fuller, G.; Garay Brignardello, Guido; Green, J.; Hindson, L.; Jones, P. A.; Lenfestey, C.; Lo, Nadia; Lowe, V.; Mardones Pérez, Diego; Menten, K.; Minier, V.; Morgan, L.; Motte, F.; Muller, E.; Peretto, N.; Purcell, C. R.; Schilke, P.; Bontemps, Schneider; Schuller, F.; Titmarsh, A.; Wyrowski, F.; Zavagno, A. (Astronomical Society of Australia, 2013)
      The Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey aims to characterise the physical and chemical evolution of high-mass star-forming clumps. Exploiting the unique broad frequency range and on-the-fly ...
    • Millimetre continuum observations of southern massive star formation regions – I. SIMBA observations of cold cores 
      Hill, T.; Burton, M. G.; Minier, V.; Thompson, M. A.; Walsh, A. J.; Hunt-Cunningham, M.; Garay Brignardello, Guido (Royal Astronomical Society, 2005)
      We report the results of a 1.2-mm continuum emission survey toward 131 star-forming complexes suspected of undergoing massive star formation. These regions have previously been identified as harbouring a methanol maser ...
    • Pilot observations for MALT-45: a Galactic plane survey at 7 mm 
      Jordan, C. H.; Walsh, A. J.; Lowe, V.; Lo, N.; Purcell, C. R.; Voronkov, M. A.; Longmore, S. N. (Oxford University Press on behalf of the Royal Astronomical Society, 2013)
      We introduce the Millimetre Astronomer’s Legacy Team – 45 GHz (MALT-45) Galactic plane survey and describe pilot survey results with the Australia Telescope Compact Array (ATCA). The pilot survey was conducted to test ...
    • Spectral imaging of the Central Molecular Zone in multiple 3-mm molecular lines 
      Jones, P. A.; Burton, M. G.; Cunningham, M. R.; Requena Torres, M. A.; Menten, K. M.; Schilke, P.; Belloche, A.; Leurini, S.; Martín Pintado, J.; Ott, Jürgen; Walsh, A. J. (2012)
      We have mapped 20 spectral lines in the Central Molecular Zone (CMZ) around the Galactic Centre, emitting from 85.3 to 93.3 GHz. This work used the 22-m Mopra radio telescope in Australia, equipped with the 8-GHz bandwidth ...
    • Star-forming protoclusters associated with methanol masers 
      Minier, V.; Burton, M. G.; Hill, T.; Pestalozzi, M. R.; Purcell, C. R.; Garay Brignardello, Guido; Walsh, A. J.; Longmore, S. (2005)
      We present a multiwavelength study of five methanol maser sites which are not directly associated with a strong (>100 mJy) radio continuum source: G31.28+0.06, G59.78+0.06, G173.49+2.42 (S231, S233IR), G188.95+0.89 ...
