We investigate the origin of elliptical galaxies, focusing primarily on star-forming galaxies in the distant Universe. We develop a model of spectral energy distributions (SEDs) to investigate the star-forming phase of elliptical galaxies, by solving the equation of radiative transfer with a consideration of the extinction and re-emission processes by dust. Furthermore, we construct an evolutionary model of SEDs in the framework of the standard model for chemical evolution. The validity of SED model is carefully examined, by comparing the model results with the observations of starburst galaxies in the local Universe. The SEDs of typical starburst galaxies Arp220 and M82 are successfully reproduced. We apply our model to two samples of nearby starburst galaxies, UV-selected starburst galaxies (UVSBGs) and ultraluminous infrared galaxies (ULIRGs). Except for galaxies hosting AGN, we successfully reproduce the observed SEDs. A wide variety of SEDs is covered with the combination of three major quantities characterizing a starburst; starburst age, compactness of starburst, and the extinction curve. By using the SED models of elliptical galaxies for both star-forming phase and passively evolving phase, we explore the fate of various star-forming galaxies at high redshifts discovered recently; i.e., whether they evolve into nearby elliptical galaxies or not.
