Star Formation and the Evolution of Galaxies

恒星的形成和星系的演化——这个项目将利用一些尖端的分子线调查来绘制星系范围内分子物质的分布，并将其与银河系更大规模的结构特征联系起来，比如旋臂和中央星系棒。这项工作将提供分子气体在整个巨分子云（GMCs）复合体（bbb100s pc）到致密团块（~ 1pc）尺度上的分布和动力学的详细图像，而致密团块是基本的恒星形成单元。将这些结果与致密团块的恒星形成特性的详细研究相结合，将提供发生在秒差距尺度上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。这将用于研究旋臂在gmc形成和恒星形成过程中所起的作用，最终推动星系演化。”

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."
