摘要
星系大尺度本动速度是研究宇宙学的一个前沿课题。它与宇宙学模型及其基本参数(例如,哈勃常数H_0、宇宙密度参数Ω等)密切有关,也与宇宙的主导物质构成及其原初密度扰动谱密切有关。本文介绍了大尺度本动速度的研究现状;概述了大尺度本动速度的测量方法和观测结果;评述了解释大尺度本动速度的流体模型和球对称模型。
The Study on large scale peculiar velocities of galaxies is an important subject for cosmology, which is closely related to the cosmological models and parameters and, obviously, also depends on the constitution of different kinds of cosmological matter. In this paper we review the recent researches for the subject both observationally and theoretically. Finally, we briefly discuss a reasonable explanation for the disagreement between observation and theory.
