Abstract: Converging flows of atomic hydrogen provide a natural mechanism to form highly structured – and turbulent – molecular clouds, due to a combination of strong thermal and dynamical instabilities. Numerical models show that specifically the dynamical instabilities can lead to a focusing of the incoming gas streams, and thus provide a very efficient mechanism to form massive protostellar cores of a few 100 M within < 10 Myr, at flow parameters typical for the Galactic disk. We will discuss the relevance of this mechanism for massive star formation, including the prediction of where massive cores would form in molecular clouds, and the resulting consequences of stellar feedback.
