Galaxy winds as a research area investigates large-scale gaseous outflows driven by processes within galaxies, such as stellar feedback from massive stars and supernovae or energy and momentum injection from active galactic nuclei. This field focuses on the multi-phase structure, kinematics, and energetics of these winds, their impact on galaxy evolution, star formation regulation, metal enrichment of the circumgalactic and intergalactic media, and the closing of the baryon cycle. Research combines observational diagnostics across the electromagnetic spectrum with theoretical modeling and simulations to quantify mass-loading factors, escape fractions, and the coupling between radiation, cosmic rays, magnetic fields, and outflowing gas.
