Work is in progress to build and make available a spectral library of galaxy models.
For the moment the spectral evolution of sample models for one elliptical and three spirals is shown and can be downloaded. M low and M sup . The files of the chemical evolution and of the SEDs of the sample models described below can be downloaded. Any model following this kind of evolutionary history reproduces the average observed SED of local giant ellipticals. Their SEDs show variations of a few orders of magnitudes in the IR and to a less extent in the optical-UV spectral region, depending on the SFR, distribution of stars and ISM, and inclination angle with respect to the line of sight.
