Description
Summary:To understand the strongly excited gas near the center of our own galaxy, detailed surveys in a variety of higher excitation states are required. To aid in this effort, the Antarctic Sub-millimeter Telescope and Remote Observatory (AST/RO, a 1.7m diameter sub-millimeter-wave telescope at the geographic South Pole) has completed a fully sampled survey of CO(7-6), CO(4-3), [CI] ( 3 P2- 3 P1), and [CI] ( 3 P1- 3 P0) in a three square degree region around the Galactic Center (Martin et al., ApJS, 150, 239 (2004)). In addition to this dataset, AST/RO has recently completed a survey area around Clump 1 and 2, thus covering the bulk of strongly excited gas near the center of the galaxy. This dataset comprises nearly a million distinct telescope pointings over many square degrees of the sky. To handle a sub-mm dataset of this size required the development of new automated observational methodologies, reduction techniques, and visualizations. These interactive 3D visualizations and movies of the full dataset are presented (when I am here at the poster) to illustrate the wealth of information available.
