Detection of Widespread Hot Ammonia in the Galactic Center

, 2013
We present the detection of metastable inversion lines of ammonia from energy levels high above the ground state. We detect these lines in both emission and absorption toward fifteen of seventeen positions in the central 300 parsecs of the Galaxy.
