Constraints on the star formation histories of galaxies from<i>z</i>∼ 1 to 0
We present a new method to estimate the average star formation rate per unit stellar mass (SSFR) of a stacked population of galaxies. We combine the spectra of 600–1000 galaxies with similar stellar masses and parametrize the star formation history of this stacked population using a set of exponentially declining …
