HST phot. & GMOS spectra of Lynx E & W clusters

Few detailed investigations of stellar populations in passive galaxies beyond z~1 are based on deep spectroscopic observations, due to the difficulty in obtaining such data. We...由于获取深度光谱观测（deep spectroscopic observations）数据存在困难，针对红移z≈1以外的宁静星系（passive galaxies）内恒星种群（stellar populations）所开展的详细研究，极少采用此类观测作为研究基础。我们……
