Scientific paper

We present results from an ongoing near-infrared survey of protostellar shock activity. This survey utilizes one of the original 2MASS cameras which has been retrofitted with narrowband near-infrared filters in three paths (H2 (2.12 microns), Fe+ (1.64 microns), and Paschen beta (1.28 microns)), allowing us to obtain images simultaneously in each filter. Observations have been made over the last year using the refurbished 2MASS camera at the Steward Observatory 61" Kuiper Telescope. We collected images of a sample of star forming regions spanning age, mass, richness, and evolutionary state in order to analyze the shock activity, derive shock parameters, and describe the energetics of the outflow and feedback on the natal cloud. Results from the first phase of this survey will be discussed.
