Title: Towards an Understanding of Star Formation in the Galactic Center

Abstract: The Galactic center is a complex laboratory containing a multitude of astrophysical phenomena. We propose to use the narrow band imaging capabilities of ISPI to enhance our understanding of the crucial links between two of these phenomena: that between hot young stars and their adjacent molecular clouds. We propose to map the inner ~50\times70 pc of the Galaxy with the narrow band Br(gamma) (2.166 \micron) and H_2 (2.121 \micron) filters to probe the molecular and ionized gas, and enhance our understanding of their relation to emission line stars throughout the region. In addition, we will use the narrow band H_2 (2.252 \micron) filter at two locations coincident with previously known H_2 (2.121 \micron) emission, to address whether the emission is produced by fluorescent or shocked gas. When combined with our recently obtain \itSpitzer Space Telescope IRAC maps of the central 1.5^o\times2.0^o of the Galaxy, the proposed observations will significantly enhance our understanding of star formation in this enigmatic region.
