Galaxy merger
Galaxy merger refers to the interaction and eventual combination of two or more galaxies due to gravitational attraction. It is associated with structural transformation, star formation activity, and changes in galactic dynamics.
Galaxy mergers are discussed in astrophysics, extragalactic astronomy, and cosmology.
Status
Galaxy mergers are observed at various stages through imaging and spectroscopic surveys. Models examine their frequency, dynamical evolution, and role in galaxy growth and morphological change.
