Galactic Chemical Evolution

Stars and interstellar gas in galaxies exhibit diverse chemical
element abundance patterns that are shaped by their
environment and formation histories. The aim of Galactic
Chemical Evolution (GCE) is to use the observed abundances
to unlock earlier epochs in the Universe, probe the
mechanisms of galaxy formation, and gain insight into the
evolution of stellar systems.
