The mass-metallicity relation refers to the correlation between the mass of a galaxy and its metallicity, or the abundance of elements heavier than helium. Specifically, the mass-metallicity relation describes how the metallicity of a galaxy increases with its stellar mass. This relation has important implications for understanding the formation and evolution of galaxies, as well as for studying the chemical enrichment processes in the universe. Research in this area seeks to investigate the factors influencing the mass-metallicity relation and to uncover its underlying physical mechanisms.
