Research Abstract

In order to reveal the history of star formation and heavy element production in the Universe, we have constructed a radiation model of galaxies consistent with the chemical evolution, i. e., the evolution of the amount of heavy elements. We then compared the model with multiwavelength observational datasets from ultraviolet to infrared wavelengths to examine the validity of the model, and succeeded in establishing the galaxy evolution model with dust production which can be applied to observational data at any age of galaxies.
