Scientific paper

Massive early-type galaxies at intermediate redshift provide a unique perspective on star formation at early times. The rest-frame UV spectra of passively evolving systems provide constraints on the formation redshift and abundances for the oldest stars at a time when the universe was roughly 1/3 its present age. The passive galaxies have spectra characteristic of F stars with strong absorption from Mg II, Mg I and Fe II. Best fitting ages are in the 1-3 Gyr range and models with solar or super-solar abundances are preferred. These properties point towards an early formation epoch and rapid down-sizing in the star formation rate.
