HCN is considered to be a very good tracer of dense gas in both the Milky Way and external galaxies is linearly correlated with star formation rates from size scale from dense clumps to whole galaxies. This star formation relationship covers 10 orders of magnitude in both mass and luminosity. Despite this strong correlation the link between star formation and the availability of dense gas is not fully understood. We will take advantage of recent Galactic plane surveys to investigate the relationship between HCN and star formation to investigate this relationship and identify the physical connection between the two.

在银河系和外部星系中，HCN被认为是一种非常好的致密气体示踪剂，它与从大小到致密团团到整个星系的恒星形成率呈线性相关。这个恒星形成关系涵盖了质量和光度的10个数量级。尽管有这种强烈的相关性，但恒星形成和稠密气体的可用性之间的联系还没有完全被理解。我们将利用最近的银河系平面调查来研究HCN和恒星形成之间的关系，以研究这种关系并确定两者之间的物理联系。
