Star Formation and the Evolution of Galaxies

恒星形成和星系演化-这个项目将利用一些尖端的分子线测量来绘制整个银河系分子物质的分布图，并将其与银河系更大尺度的结构特征联系起来，如旋臂和中央银河条。这项工作将提供整个巨型分子云(GMCS)复合体(&GT；100S PC)到密团(~1PC)尺度上分子气体的分布和动力学的详细图像，这是恒星形成的基本单位。将这些结果与对致密团块恒星形成特性的详细研究相结合，将提供在微秒尺度上发生的恒星形成与银河系大尺度动力学(KPC尺度)之间的物理联系。这将被用来研究旋臂在GMC的形成和恒星形成过程中所扮演的角色，而恒星形成过程最终推动了银河系的进化。

Star Formation and the Evolution of Galaxies - This project will utilise a number of cutting edge molecular line surveys to map the Galaxy-wide distribution of molecular material and link this to the larger scale structural features of the Milky Way, such as the spiral arms and central Galactic bar. This work will provide a detailed picture of the distribution and dynamics of the molecular gas on scales of whole giant molecular cloud (GMCs) complexes (>100s pc) down to the scales of dense clumps (~1 pc), which is the fundamental star-forming unit. Combining these results with detailed studies of the star forming properties of dense clumps will provide a physical link between star formation taking place on parsec scales and the large-scale dynamics of the Milky Way (kpc scales). This will be used to investigate the role spiral arms play in the formation of GMCs and in the star formation processes, which ultimately drives galactic evolution."
