标题： Recent Advances in Redshift Surveys of the Local Universe

摘要： 我回顾了过去几年中通过星系红移巡天研究宇宙大尺度结构的进展。在描述星系分布的各种统计方法中，我集中讨论了功率谱，并详细介绍了那些使对其解释复杂化（同时也使其变得有趣）的因素，例如红移空间扭曲、非线性效应以及星系和暗物质之间的相对偏倚。我还讨论了两个刚刚开始的大规模红移巡天项目，即斯隆数字巡天和两度域红移巡天，它们有望将均匀巡天中测量到的星系红移数量增加一个数量级以上。 显示英文摘要

摘要： I review progress in the past few years in studying the large-scale structure of the universe through redshift surveys of galaxies. Of the many statistical methods used to describe the galaxy distribution, I concentrate here on the power spectrum, and go into some detail about the factors which complicate (and make interesting!) its interpretation, such as redshift space distortions, non-linear effects, and the relative bias of galaxies and dark matter. I also discuss two large redshift surveys which are just starting, the Sloan Digital Sky Survey, and the Two Degree Field Redshift Survey, which promise to increase the number of redshifts measured of galaxies in uniform surveys by more than an order of magnitude.
