Star formation in collapsing proto-clusters Hans Zinnecker DSI, Stuttgart, DE
Infall signatures (red shifted absorption of NH3 rotational transitions) of neutral gas onto bright dust continuum clumps have been detected with SOFIA GREAT at 1.81 THz in a number of cases in APEX/ATLASGAL GPS sources. High accretion rates of the order of 10-3 Msol/yr have been derived. This new observational techniques holds great promise for understanding the early phases of clustered star formation. Follow-up high spatial resolution submm imaging of these proto-clusters is now needed to study the fragmentation process into low- and high-mass proto-stars.
