Massive stars are powerful and dynamic energy sources for the interstellar medium, capable of hindering star formation through molecular cloud dissolution or acting as a catalyst through cloud compression. Studying the radiative and mechanical feedback processes of massive stars on their environments therefore yields information about the evolution of the interstellar medium. In a sense, this SOFIA Legacy Program is the expansion of the study of the Orion Nebula published in Nature  to other massive star-forming regions in our galaxy. This program will survey 11 regions including quintessential representatives of their type, including single O- or B-stars, small groups of O stars, rich stellar clusters, and mini starbursts, for a big-picture look at the interaction of massive stars with the interstellar medium throughout the universe.

The introduction paper (Schneider et al., 2020)  is available here 2020arXiv200908730S., with an initial analysis of the RCW120 map: "FEEDBACK: a SOFIA Legacy Program to Study Stellar Feedback in Regions of Massive Star Formation", Schneider, N., et al., 2020/09, arXiv200908730S, DOI: 10.1088/1538-3873/aba840. Also see X. Tielens interview on Astrobites.

The preliminary maps are available in the archive! Initial [CII] and [OI] data cubes for RCW79, RCW49, RCW36, RCW120, NGC7538, NGC6334, CYGNUS X, M40, M16 and M17 are available for download. These incomplete maps will be filled after missing fields are observed in the remainder of Cycle 8.
