摘要

As part of the DEEP2 galaxy redshift survey, we analyze absorption line strengths in stacked Keck DEIMOS spectra of red field galaxies with weak to no emission lines, at redshifts. Comparison with models 0.7 <= z <= 1 of stellar population synthesis shows that red galaxies at have mean luminosity-weighted ages of the z similar to 0.9 orde...更多
