Emission in the H2 1-0S(1) line at 2.122 micron is a powerful tracer of shock excitation in these objects. Here we present the analysis of 1.3 x 0.9 square degrees data from the UK Widefield Infrared Survey for H2 (UWISH2) in the 1-0S(1) line to identify and characterize the outflows of the W51 complex. We found 39 individual knots in the complex. We identified driving source candidates of the outflows and found that most of them are protostars. We fit SED models to the candidate outflow driving sources and conclude that the outflows of our sample are mostly driven by moderate-mass YSOs that are still actively accreting from their protoplanetary disc. We discuss that several of our newly identified outflow candidates are excellent targets for follow up studies to better understand very early phase of protostellar evolution |
