Poster Title: Retrieving the star formation history of the SDSS-EDR galaxies
Abstract: We fit the stellar continuum of the SDSS EDR galaxies on high resolution population synthesis models to constrain in a non-parametric way the star formation history of the galaxies selected by mass and morphology. For this purpose we use MOPED, an optimal, linear compression algorithm, to single out the most valuable features in the high frequency part of the spectra. We find that almost all massive ellipticals have completed the bulk of their star formation by z=1.4 while the majority of spirals shows fairly constant star formation.
