We have been awarded (and scheduled over 6 nights) 22 hours of observing time at the JCMT in Hawaii, for project m15ai143. Theoretical and observational studies show that CS is a good tracer of dense gas. A mapping of the starburst galaxy NGC 6946 has been completed for low-J transitions of CS using IRAM-30m. These have been used to determine the properties of the dense, star-forming gasacross the galaxy. In order to improve these calculations, we were awarded time to observe the samelocations of NGC 6946 in high-J transitions. This will pave the way for a potential surveymapping nearby galaxies in CS. We are requesting travel and subsistence money for George Kelly to go observing at the JCMT (note that we have been scheduled in just over 1 month time and we have only been told few days ago about it - hence the requested budget for the flight is quite expensive (the quoted price from our travel agency is 1500 pounds for the dates we needed.).

我们在夏威夷的JCMT获得了22小时的观测时间（计划超过6个晚上），用于项目m15 ai 143。理论和观测研究表明，CS是致密气体的良好示踪剂。利用IRAM-30 m完成了对NGC 6946星暴星系CS低J跃迁的测绘。这些已经被用来确定整个星系中致密的恒星形成气体的性质。为了改进这些计算，我们获得了时间来观察NGC 6946在高J跃迁中的相同位置。这将为在CS中对附近星系进行潜在的测绘铺平道路。我们正在为乔治凯利申请旅行和生活费，以便他去观察JCMT（请注意，我们已经安排了一个多月的时间，我们几天前才被告知-因此，要求的飞行预算是相当昂贵的（我们的旅行社报价是1500英镑，我们需要的日期）。
