The environmental (inter)dependence of pre-supernova feedback
Feedback from massive stars plays a central role in shaping the evolution of galaxies. Conversely, different galactic environments play a central role in regulating the impact of massive stars. Yet, despite a solid qualitative understanding of feedback, our quantitative knowledge remains poor. Until recently, only a few star-forming regions had adequate observational information on gas and stars needed for detailed stellar feedback studies.
Over the past decade, integral field units (IFUs) have revolutionized our approach to resolved stellar feedback studies in nearby galaxies. In this talk, I will present recent results of large IFU nearby galaxy surveys and discuss how these enable an empirical quantification of the interdependence between stellar feedback and the environments massive stars form in. They also allowquantifying the importance of pre-supernova feedback in regulating the impact of subsequent SN explosions.
