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.

了解大质量星星形成与控制恒星形成的星际气体性质之间的相互作用，对于理解宇宙的演化至关重要。研究计划的一项内容是通过观测附近星系的毫米线分子来研究这种相互作用，这些分子是星际气体条件的示踪剂。此外，正在进行理论计算，以模拟大质量恒星形成时产生的冲击波对周围介质的激发效应。通过这种方式，它的目的是将初始气体条件与星星形成的结果区分开来，特别是在经历大质量星星形成爆发的星系中。
