在对星系团内星系演化的研究中，布彻和奥姆勒发现了恒星形成率随红移而发生强烈演化的证据。后来的研究证实了这一结论，并发现了这种效应的几个方面：光度、光谱和形态。本文回顾了这些工作的广泛样本，并讨论了可能导致恒星形成率变化的选择效应、偏差和驱动机制。
Abstract In their study of the evolution of galaxies within clusters, Butcher and Oemler discovered evidence for a strong evolution in star-formation rate with redshift. Later studies confirmed this conclusion and uncovered several aspects of the effect: photometric, spectroscopic, and morphological. This article reviews a broad sample of these works and discusses selection effects, biases, and driving mechanisms that might be responsible for the changes in star-formation rate.
