Outflows and star-formation feedback from young stellar objects in NGC1333

NGC1333 is a nearby star-forming region in Perseus which is particularly rich in Class 0/I protostars and associated outflows. We have mapped the entire NGC 1333 complex (~ 400 arcmin^2) in near- and mid- infrared spectral lines which trace the supersonic interaction of these outflows with their surroundings. Here we present new Hubble Space Telescope Wide Field Camera 3 spectral images in two [Fe II] lines and H I Pa beta, and earlier Spitzer Space Telescope Infrared Spectrograph images of many more molecular and atomic emission lines. We use these data along with detailed shock models to make accurate rate measurements of the mass, momentum, and kinetic energy deposited into the surrounding cloud by the protostellar outflows. We also determine accurately the extinction toward the shocks, which enables us to determine the location of the energy/momentum deposition in quasi-3D.
