Description

From ATCA project proposal C3145: "We are building on Australia’s rich tradition of spectral line legacy surveys to deliver a 7-mm dense gas survey of the Fourth Quadrant Galactic Plane in multiple molecular spectral lines and continuum emission. Using ATCA autocorrelation data, the "Full Strength" MALT45 will address a wide range of astrophysical challenges, including directly testing competing theories of massive star formation, mapping the dense gas structure of the Milky Way through to the far side of the Disk, and (combined with cutting-edge gamma ray data from forthcoming multi-national Cherenkov Telescope Array Observatory) constraining the location and nature of the Galaxy's cosmic ray accelerators. The survey will provide lasting legacy value to the community, via both the science carried out by the survey team, and the data products it delivers. By locking in key measurements in our "astronomical backyard", the project will provide a crucial astrophysical template that will allow us to interpret future sensitive, high resolution surveys of external galaxies with ALMA and the SKA.". We propose reducing StarFISH data to create Galactic Plane maps as ancillary data to CTA observations
