Abstract: As we look for redshifted mm and sub-mm radio emission in distant galaxies, we need to understand our own Galaxy’s emission to serve as a comparison. To aid in this effort, the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO) has completed a survey of CO(7–6), CO(4– 3), [CI] (3P23P1), and [CI] (3P13P0) from a three square degree region around the Galactic Center. In addition to this dataset, AST/RO has recently completed a survey area around Clumps 1 and 2, thus covering the bulk of strongly excited gas near the center of the Galaxy. Using this dataset, we explain the variety of features in our own Galaxy and how they can be used to interpret the data that will be collected using future observations of distant galaxies.
