Scientific paper

The present study of the photometric evolution of spiral galaxies after either simple or infall formation and of various Schmidt-type star-formation laws notes that, irrespective of galaxy and star formation law assumptions, nearly identical luminosity evolution is obtained for each morphological type as a function of the look-back time until the epoch corresponding to the average age of stars in a galaxy. Beyond that epoch, the luminosity evolution is found to significantly depend on the context of galaxy formation. With a view to the use of the models in cosmological studies, the evolving spectral energy distributions of spiral galaxies for all the cases studied are presented in tabular form.
