Scientific paper

We propose to use Camera 3 of NICMOS in order to study the distribution of molecular hydrogen in the circumnuclear ring that engulfs the inner 2 parsecs of the Galaxy. These observations will be combined with approved Cycle 7 FeII line observations of a similar region using the same camera to address the roles played by UV and shock excitation of the gas. The H_2 observations will provide a direct measure of the degree of clumpiness within the ring. The proposed observations will be able to resolve the individual clumps and will have powerful implications in our understanding of the sources of outflow, dynamics and formation of the ring within the inner two parsecs of the Galaxy.
