Abstract
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 gas
across the galaxy. In order to improve these calculations, we were awarded time to observe the same
locations of NGC 6946 in high-J transitions. This will pave the way for a potential survey
mapping 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.).

| Description | This was a PATT grant so only provided money for an observing trip. We observed two transitions of the CS line in 2 galaxies. The work contributed to produce the CS ladder needed to determine the excitation properties of starburst galaxies. |
| Exploitation Route | The data will be published and in any case will be retained in the JCMT archive where everyone can access them. |
