[44.04] New Fully-Sampled Maps of the Galactic Center Region in CO(7-6), CO(4-3), and [CI]

We have imaged a three-quarter of a square degree region around the Galactic Center in the CO(7-6), CO(4-3), CI(³P₂-³P₁), and CI(³P₁-³P₀) transitions using the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO). The data are fully-sampled and have a velocity resolution of 0.6 km s^-1. These maps show greater detail over a considerably larger region than has been mapped previously by ourselves or other groups. Bright CO(7-6) emission is detected in the well-known Galactic Center clouds Sgr A and Sgr B. We also detect CO(4-3) absorption at v_LSR = -4 km s^-1 along the line of sight toward the Galactic Center. Using a comparison of the CO(7-6) and CO(4-3) intensities with observations of CO(1-0) and ¹³CO(1-0), an LVG model is applied to estimate the kinetic temperature and density of the entire mapped region.
