Mapping CS in starburst galaxies: Disentangling and characterising dense gas

我们已经被授予(并计划超过6个晚上)22小时的观测时间，在夏威夷的JCMT，项目m15ai143。理论和观测研究表明，CS是一种很好的稠密气体示踪剂。用IRAM-30M完成了星暴星系NGC6946的CS低J跃迁的测绘。这些已经被用来确定整个银河系中形成恒星的致密气体的性质。为了改进这些计算，我们获得了时间来观察NGC6946在高J相变中的相同位置。这将为潜在的对CS附近星系的探测铺平道路。我们要求乔治·凯利前往JCMT观察的旅费和生活费(请注意，我们的日程安排在一个多月后，我们几天前才被告知-因此要求的航班预算相当昂贵(我们旅行社的报价是1500英镑，我们需要的日期)。

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.).
