摘要在这篇文章中，我们回顾了莱曼破裂星系的性质，即高红移的星爆星系，大约在2：52：5的范围内，包括1000个光谱红移和另外几千个强健的候选者。这一数据集使我们能够以哈勃时间的20%或更短的时间前所未有地观察星系的基本性质。本文讨论了Lyman破裂星系的性质及其性质，包括恒星形成率、恒星和总质量、化学丰度、形态和星际介质(ISM)运动学，并概述了它们对宇宙恒星含量的贡献以及它们与当今宇宙中观测到的星系的联系。我们还讨论了这些星系的性质，特别是它们的空间星团，对于星系形成的机制，以及暗物质的潜在分布和恒星形成活动之间的关系。
■ Abstract In this paper we review the properties of Lyman-break galaxies, namely starburst galaxies at high redshifts, approximately in the range 2:5 2:5, including1000 spectroscopic redshifts and another few thousands of robust candidates. This dataset has allowed us an unprecedented look at fundamental properties of galaxies at 20% of the Hubble time or less. In this paper, we discuss the nature of the Lyman-break galaxies and their properties, including star-formation rate, stellar and total mass, chemical abundance, morphology, and interstellar medium (ISM) kinematics, and outline their contribution to the stellar content of the universe and their connection to the galaxies observed in the present-day universe. We also discuss what the properties of these galaxies, in particular their spatial clustering, imply about the mechanisms of galaxy formation and about the relationship between the underlying distribution of dark matter and the activity of star formation.
