Title: Energy Feedback via Shocks in Starburst Environments: the Case of 30 Doradus

Abstract: We propose to image the entire 30 Doradus nebula in the [FeII] emission line at 1.64\micron with NEWFIRM on the CTIO 4-m telescope. The proposed observation will reveal the spatial distribution of shocks in the region, which serves as a strong complement to the NEWFIRM H_2 and Br(gamma) images we already obtained, and our proposed spectroscopic observations using the NTT. We aim to quantify the fraction of each energy input (shock and radiation) in the 30 Doradus PDR with the H_2/Br(gamma), [FeII]/H_2, and [FeII]/Br(gamma) ratios, and to ultimately better understand subsequent star formation in starburst regions.
