Patiently watching jets giving feedback

Feedback by protostellar jets may substantially impact the outcome of star formation within a cloud. This can happen on a variety of scales, from disk winds extracting angular momentum and allowing for accretion through the disk, to carving cavities into protostellar envelopes and cores, to driving turbulence within the parent clouds. We present first results from a wide field survey for proper motions of shocks in protostellar outflows, with epochs separated by as much as 2-3 decades, covering a significant portion of the Orion A giant molecular cloud. The survey is designed to reveal proper motions of a full protostellar jet population within a cloud, complementing higher-resolution, smaller field measurements (e.g., ALMA, JWST) of jet feedback on smaller scales.
