      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 - 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 ...
    • ATLASGAL – properties of compact H II regions and their natal clumps 
      Urquhart, J.; Thompson, M.; Moore, T.; Purcell, C. R.; Hoare, M.; Schuller, F.; Wyrowski, F.; Csengeri, T.; Menten, K.; Lumsden, S. L.; Kurtz, S.; Walmsley, C. M.; Bronfman Aguiló, Leonardo; Morgan, L.; Eden, D.; Russeil, D. (Royal Astronomical Society, 2013-08-19)
      We present a complete sample of molecular clumps containing compact and ultracompact H II (UC H II) regions between = 10◦ and 60◦ and |b| < 1◦, identified by combining the APEX Telescope Large Area Survey of the Galaxy ...
    • ATLASGAL – The APEX telescope large area survey of the galaxy at 870 μm

(ESO, 2009-02-20)
      Context. Thanks to its excellent 5100 m high site in Chajnantor, the Atacama Pathfinder Experiment (APEX) systematically explores the southern sky at submillimeter wavelengths, in both continuum and spectral line emission. ...
    • ATLASGAL – towards a complete sample of massive star forming clumps 
      Urquhart, James; Moore, Toby; Csengeri, Timea; Wyrowski, Friedrich; Schuller, Frederic; Hoare, Melvin G.; Lumsden, Stuart; Mottran, Josep; Thompson, Mark; Menten, Karl; Walmsley, C. M.; Bronfman Aguiló, Leonardo; Pfalzner, Susana; König, Carsten; Wienen, Marion (Royal Astronomical Society, 2014)
      By matching infrared-selected, massive young stellar objects (MYSOs) and compact H II regions in the Red MSX Source survey to massive clumps found in the submillimetre ATLASGAL (APEX Telescope Large Area Survey of the ...
    • Characterization of infrared dark clouds 
      Chira, R. A.; Beuther, H.; Linz, H.; Schuller, F.; Walmsley, C. M.; Menten, K. M.; Bronfman Aguiló, Leonardo (2013)
      Context. Despite increasing research in massive star formation, little is known about its earliest stages. Infrared dark clouds (IRDCs) are cold, dense and massive enough to harbour the sites of future high-mass star ...
