      We have developed an iterative procedure to systematically combine the millimeter and submillimeter images of OB cluster-forming molecular clouds, which were taken by ground-based (CSO, JCMT, APEX, and IRAM-30 m) and space ...

    • Connecting the dots: a correlation between ionizing radiation and cloud mass-loss rate traced by optical integral field spectroscopy

      We present an analysis of the effect of feedback from O- and B-type stars with data from the integral field spectrograph Multi Unit Spectroscopic Explorer (MUSE) mounted on the Very Large Telescope of pillar-like structures ...

    • Dense gas in the Galactic central molecular zone is warm and heated by turbulence 

      Ginsburg, A.; Henkel, C.; Ao, Y.; Riquelme, D.; Kauffmann, J.; Pillai, T.; Mills, E.~A.~C.; Requena-Torres, M.~A.; Immer, K.; Testi, L.; Ott, J.; Bally, J.; Battersby, C.; Darling, J.; Aalto, S.; Stanke, T.; Kendrew, S.; Kruijssen, J.~M.~D.; Longmore, S.; Guesten, R.; Menten, K.~M.; Dale, James (2016-01-26)
      Context. The Galactic center is the closest region where we can study star formation under extreme physical conditions like those in high-redshift galaxies. Aims. We measure the temperature of the dense gas in the central ...

    • The dynamical evolution of molecular clouds near the Galactic Centre - II. Spatial structure and kinematics of simulated clouds 

      Kruijssen, J. M. D.; Dale, J. E.; Longmore, S. N.; Walker, D. L.; Henshaw, J. D.; Jeffreson, S. M. R.; Petkova, M. A.; Ginsburg, A.; Barnes, A. T.; Battersby, C. D.; Immer, K.; Jackson, J. M.; Keto, E. R.; Krieger, N.; Mills, E. A. C.; Sánchez-Monge, Á.; Schmiedeke, A.; Suri, S. T.; Zhang, Q. (2019-04-21)
      The evolution of molecular clouds in galactic centres is thought to differ from that in galactic discs due to a significant influence of the external gravitational potential. We present a set of numerical simulations of ...

    • Feedback from massive stars at low metallicities : MUSE observations of N44 and N180 in the Large Magellanic Cloud 

      McLeod, A. F.; Dale, J. E.; Evans, C. J.; Ginsburg, A.; Kruijssen, J. M. D.; Pellegrini, E. W.; Ramsay, S. K.; Testi, L. (2018-10-05)
      We present MUSE integral field data of two HII region complexes in the Large Magellanic Cloud (LMC), N44 and N180. Both regions consist of a main superbubble and a number of smaller, more compact HII regions that formed ...

    • The ionised, radical and molecular Milky Way: spectroscopic surveys with the SKA
