    • ALMA survey of massive cluster progenitors from ATLASGAL: Limited fragmentation at the early evolutionary ... 
      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 ...
    • Episodic accretion constrained by a rich cluster of outflows 
      Nony, T.; Motte, F.; Louvet, F.; Plunkett, A.; Gusdorf, A.; Fechtenbaum, S.; Pouteau, Y.; Lefloch, B.; Bontemps, S.; Molet, J.; Robitaille, J-F (EDP Sciences, 2020)
      Context. The accretion history of protostars remains widely mysterious, even though it represents one of the best ways to understand the protostellar collapse that leads to the formation of stars.Aims. Molecular outflows, ...
    • Large scale map of millimeter wavelength hydrogen radio recombination lines around a young massive star cluster 
      Nguyen Lu'o'ng, Q.; Anderson, L. D.; Motte, F.; Louvet, F.; Bronfman Aguiló, Leonardo (IOP Publishing Ltd, 2017)
      We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main young massive star cluster (YMC). Our mm-RRL ...
    • Outflows, cores, and magnetic field orientations in W43-MM1 as seen by ALMA 
      Arce Tord, C.; Louvet, F.; Cortés, P. C.; Motte, F.; Hull, C. L. H.; Le Gouellec, V. J. M.; Garay, G.; Nony, T.; Didelon, P.; Bronfman Aguiló, Leonardo (EDP Sciences, 2020)
      Aims. It has been proposed that the magnetic field, which is pervasive in the interstellar medium, plays an important role in the process of massive star formation. To better understand the impact of the magnetic field at ...
    • The earliest phases of high mass star formation, as seen in NGC 6334 by Herschel HOBYS 
      Tige, J.; Motte, F.; Russeil, D.; Louvet, F. (EDP Sciences, 2017)
      Aims. To constrain models of high-mass star formation, the Herschel-HOBYS key program aims at discovering massive dense cores (MDCs) able to host the high-mass analogs of low-mass prestellar cores, which have been searched ...
    • The unexpectedly large proportion of high-mass starforming cores in a Galactic mini-starburst 
      Motte, F.; Nomy, T.; Louvet, F.; Marsh, K.A.; Bontemps, S.; Whitworth, A. P.; Men’shchikov, A.; Nguyen Luong6, Q.; Csengeri, T.; Maury, A. J.; Gusdorf, A.; Chapillon, E.; Könyves, V.; Schilke, P.; Duarte Cabral, A.; Didelon, P.; Gaudel, M. (Springer Nature, 2018)
      Understanding the processes that determine the stellar Initial Mass Function (IMF) is a critical unsolved problem, with profound implications for many areas of astrophysics1. In molecular clouds, stars are formed in cores, ...
    • Tracing extended low-velocity shocks through SiO emission Case study of the W43-MM1 ridge 
      Louvet, Fabien; Motte, F.; Gusdorf, A.; Lu'o'ng, Q. Nguyen; Lesaffre, P.; Duarte Cabral, A.; Maury, A.; Schneider, N.; Hill, T.; Schilke, P.; Gueth, F. (EDP Sciences, 2016)
      Aims. Previous literature suggests that the densest structures in the interstellar medium form through colliding flows, but patent evidence of this process is still missing. Recent literature proposes using SiO line emission ...
