Welcome to FANG!
What drives the evolution of galaxies? One of the most important
factors is energetic feedback from massive stars. The hottest, most
massive stars produce vast quantities of UV ionizing
radiation, and end their short lives as supernova explosions. These
shocks generate hot gas in galaxies and synthesize the chemical
elements in the universe. The stars themselves are also responsible
for photoionizing discrete nebulae, diffuse interstellar medium, and
the early cosmos itself. All of 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 group, Feedback Activity in Nearby Galaxies
(FANG), focuses on this massive star feedback
to the interstellar and intergalactic medium, on local, global, and
- Massive stars and clusters
- Radiative feedback: HII regions, Lyman continuum-emitting galaxies
- Kinematic feedback: Supernova-driven superbubbles and
- Chemical feedback: Enrichment processes and galactic chemical evolution
