Title: Star formation in the Central Molecular Zone: Massive Outflows in Sgr C

Abstract: We propose to measure the population of YSOs with active molecular hydrogen outflows in the Sgr C complex. Recently obtained long slit spectroscopy of G359.44-0.102 show H_2 and Br(gamma) emission from several knots within the emission region of this Spitzer-detected ``Extended Green Object" (EGO), providing strong evidence for the presence of outflows. \textbfG359.44-0.102, located on the outskirts of the Sagittarius C complex, is the first confirmed massive outflow in the east side of the CMZ. These same long-slit spectra serendipitously revealed another outflow ~ 30\arcsec away, separated by ~75 km s^-1 and associated with an entirely different star forming region. These detections imply that there is vigorous yet undiscovered star formation in the Sgr C complex. A wide-field H_2 and Br(gamma) imaging study is warranted to characterize the outflow population in the supposedly quiescent half of the Central Molecular Zone.
