摘要: We combine ultradeep optical spectroscopy from the GMASS project ("Galaxy Mass Assembly Spectroscopic Survey") with GOODS multi-band photometry and HST imaging to study a sample of passive galaxiesat 1.39 2. These galaxies have morphologies that are predominantly compact spheroidal.However, their sizes (R_e 1, absent if R_e The results compared theoretical models main implications discussed in framework massive galaxy formation evolution.
