Galaxy evolution
Appearance
Galaxy evolution refers to the changes in the physical properties of galaxies over cosmic time. It encompasses processes affecting structure, stellar populations, gas content, and dynamical behavior.
Galaxy evolution is discussed in astrophysics, cosmology, and extragalactic astronomy.
Status
Galaxy evolution is investigated through observations of galaxies at different redshifts and through numerical simulations. Models examine the roles of mergers, star formation, feedback, and environmental effects, and remain under active development.
