The evolution of young HII regions
P. D. Klaassen, K. G. Johnston, J. S. Urquhart +6
High-mass stars form in much richer environments than those associated with isolated low-mass stars, and once they reach a certain mass, produce ionised (HII) regions. The formatio…

With the GREAT receiver at the Stratospheric Observatory for Infrared Astronomy (SOFIA), nine massive molecular clumps have been observed in the ammonia line at 1.…
A distance limited sample of massive star forming cores from the RMS survey
L. T. Maud, S. L. Lumsden, T. J. T. Moore +3
We analyse CO (2) data from a sample of 99 infrared-bright massive young stellar objects (MYSOs) and compact HII regions that were identified as potential molecular-ou…
Infrared dark clouds on the far side of the Galaxy
A. Giannetti, F. Wyrowski, S. Leurini +5
Context: Infrared dark clouds are the coldest and densest portions of giant molecular clouds. The most massive ones represent some of the most likely birthplaces for the next gener…
