      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, ...
    • ALMA survey of massive cluster progenitors from ATLASGAL: Limited fragmentation at the early evolutionary stage of massive clumps 

      Csengeri, T.; Bontemps, S.; Wyrowski, F.; Motte, F.; Menten, K. M.; Beuther, H.; Bronfman Aguiló, Leonardo; Commerçon, B.; Chapillón, E.; Duarte Cabral, A.; Fuller, G. A.; Henning, Th; Leurini, S.; Longmore, S.; Palau, A.; Peretto, N.; Schuller, F.; Tan, J. C.; Testi, L.; Traficante, A.; Urquhart, J. S. (EDP Sciences, 2017)
      The early evolution of massive cluster progenitors is poorly understood. We investigate the fragmentation properties from 0.3 pc to 0.06 pc scalesof a homogenous sample of infrared-quiet massive clumps within 4.5 kpc ...
    • ATLASGAL - compact source catalogue: 330 degrees < l < 21 degrees 

      Contreras, Y.; Schuller, F.; Urquhart, J. S.; Csengeri, T.; Wyrowski, F.; Beuther, H.; Bontemps, S.; Bronfman Aguiló, Leonardo; Henning, Thomas; Menten, K. M.; Schilke, P.; Walmsley, C. M.; Wienen, M.; Tackenberg, J.; Linz, H. (EDP Sciences, 2012-10-24)
      Context. The APEX Telescope Large Area Survey of the GALaxy (ATLASGAL) is the first systematic survey of the inner Galactic plane in the sub-millimetre. The observations were carried out with the Large APEX Bolometer Camera ...
    • ATLASGAL - Complete compact source catalogue: 280°<ℓ< 60° 

      Urquhart, J. S.; Csengeri, T.; Wyrowski, F.; Schuller, F.; Bontemps, S.; Bronfman Aguiló, Leonardo; Menten, K. M.; Walmsley, C. M.; Contreras, Y.; Beuther, H.; Wienen, M.; Linz, H. (EDP Sciences, 2014)
      Context. The APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) is the largest and most sensitive systematic survey of the inner Galactic plane in the submillimetre wavelength regime. The observations were carried ...
    • ATLASGAL - environments of 6.7 GHz methanol masers 

      Urquhart, J. S.; Moore, T. J. T.; Schuller, F.; Wyrowski, F.; Menten, K. M.; Thompson, M. A.; Csengeri, T.; Walmsley, C. M.; Bronfman Aguiló, Leonardo; König, C. (Oxford University Press on behalf of the Royal Astronomical Society, 2013-03-12)
      Using the 870 mu m APEX Telescope large area survey of the Galaxy, we have identified 577 submillimetre continuum sources with masers from the methanol multibeam survey in the region 280 degrees < l < 20 degrees; vertical ...
    • ATLASGAL - Kinematic distances and the dense gas mass distribution of the inner Galaxy 

      Wienen, M.; Wyrowski, F.; Menten, K. M.; Urquhart, J. S.; Csengeri, T.; Walmsley, C. M.; Bontemps, S.; Russeil, D.; Bronfman Aguiló, Leonardo; Koribalski, B. S.; Schuller, F. (EDP Sciences, 2015)
      Context. The formation of high mass stars and clusters occurs in giant molecular clouds. Objects in evolved stages of massive star formation such as protostars, hot molecular cores, and ultracompact HII regions have been ...
    • 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 ...
    • SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium 

      Schuller, F.; Csengeri, T.; Urquhart, J.S.; Duarte Cabral, A.; Barnes, P.J.; Giannetti, A.; Hernandez, A.K.; Leurini, S.; Mattern, M.; Medina, S. -N.X.; Agurto, C.; Azagra, F.; Anderson, L.
