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.).

我们已为 m15ai143 项目获得了在夏威夷 JCMT 的 22 小时观测时间（并安排了 6 个晚上）。理论和观测研究表明CS是一种良好的致密气体示踪剂。使用 IRAM-30m 完成了星暴星系 NGC 6946 的 CS 低 J 跃迁测绘。这些已被用来确定整个星系中致密的恒星形成气体的特性。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 中绘制附近星系的潜在勘测铺平道路。我们正在为乔治·凯利申请前往 JCMT 观察的旅费和生活费（请注意，我们的预定时间只有 1 个多月，而且几天前才被告知 - 因此，所要求的航班预算相当多）价格昂贵（我们旅行社的报价是我们需要的日期 1500 英镑。）。
