An understanding of the interplay between massive star formation and the properties of the interstellar gas which control it is crucial to comprehending the evolution of the universe. An element of the research plan is to investigate this interaction by observations of nearby galaxies in the millimetre lines of molecules which are tracers of conditions in the interstellar gas. In addition, theoretical computations are being undertaken to simulate the excitation effects of the shock waves produced by the formation of massive stars on the surrounding medium. In this way, it is intended to separate initial gas conditions from those that are the consequences of star formation, especially in galaxies undergoing bursts of massive star formation.

了解大规模恒星形成与星际气体的性质之间的相互作用，这对于理解宇宙的演变至关重要。研究计划的一个要素是通过在分子的毫米线中观察到附近星系的观察，这些星系是星际气体中条件的示踪剂。此外，还进行了理论计算，以模拟通过周围介质上大型恒星形成产生的冲击波的激发效应。这样，它旨在将初始气体条件与恒星形成后果的气体条件分开，尤其是在经历大型恒星形成的星系中。
