Spectroscopy of galaxies in z=0.2-0.9 clusters

We present an analysis of stellar populations in passive galaxies in seven massive X-ray clusters at z=0.19-0.89. Based on absorption-line strengths measured from our high...本研究针对红移z=0.19~0.89区间内的7个大质量X射线星系团（X-ray clusters）中的被动星系（passive galaxies）的恒星种群（stellar populations）展开分析。基于我们通过高（原文未完整给出后续修饰内容）测得的吸收线强度...
