摘要

观测到的星系服从一组严格的动态标度关系。我们回顾了几十年来旋转支持的盘状星系在质量、表面亮度和气体含量方面的这些关系。这些千差万别的系统的行为可以用几个由一个共同的加速度尺度连接起来的经验规律来概括。

Dynamical Regularities in Rotating Galaxies.

Galaxies are observed to obey a strict set of dynamical scaling relations. We review these relations for rotationally supported disk galaxies spanning many decades in mass, surface brightness, and gas content. The behavior of these widely varied systems can be summarized with a handful of empirical laws connected by a common acceleration scale.
