 Population synthesis is a theoretical framework used to interpret the integrated spectra of galaxies as the sum of light emitted by their constituent stellar populations. Because the light of "normal" galaxies originates almost entirely from stars, and stellar evolution is relatively well-understood, astronomers can model a galaxy's spectral energy distribution (SED) by simulating its history of star formation and chemical enrichment. Population synthesis is a theoretical framework used to interpret the integrated spectra of galaxies as the sum of light emitted by their constituent stellar populations.
