What drives the evolution of galaxies? One of the most important processes is energetic feedback from massive stars. The hottest, most luminous, massive stars produce vast quantities of ultraviolet radiation, and end their short lives as supernova explosions. These explosions generate powerful shocks and create most of the chemical elements in the universe. All these effects originating from the massive star population are fundamental drivers of galaxy evolution. In addition, the relationships between stellar and gaseous galactic components on all scales form the basis for interpreting observations of galaxies and phenomena in the distant universe.

Sally Oey's research interests focus on this massive star feedback to the interstellar and intergalactic medium, on local, global, and cosmic scales.

• Chemical feedback: Enrichment processes and galactic chemical evolution
• Radiative feedback: HII nebulae and photoionized gas
• Kinematic feedback: Supernova-driven superbubbles and galactic superwinds
• Massive stars and associations, as the source for these processes
