Observational Assessment of Stellar Feedback in Star-Forming Regions
Laura Lopez



Stellar feedback has a profound influence in many astrophysical phenomena, yet it is often cited as one of the biggest uncertainties in star and galaxy formation models today. This uncertainty stems from a dearth of observational constraints as well as the great dynamic range between the small scales (<1 pc) over which feedback occurs and the large scales (>1 kpc) on which galaxies are shaped by that feedback. In this talk, I will show how multiwavelength observations can be used to overcome these challenges to assess the role of many stellar feedback mechanisms, including radiation, stellar winds, supernovae, and cosmic rays. I will present results from the application of these approaches to a variety of sources and discuss the implications regarding the dynamics of star-forming regions and the launching of galactic winds. Finally, I will highlight the exciting prospects of using current and upcoming facilities to explore feedback in diverse conditions.
