论文摘要
订单$ 10^{ - 10} \ Mathrm {m/s^2} $的加速度量表隐含在Baryonic Tully-Fisher和Baryonic Faber-Jackson关系中，独立于任何理论优先或偏见。我们表明，当来自压力支持的系统的数据中，包括球状簇，椭圆星系和星系簇的压力支持系统的数据，最明显的是，该量表的存在最为明显。这表明加速度比例$ 10^{ - 10} \ mathrm {m/s^2} $与在许多不同的长度尺度上结构形成过程的相关性，并且可以指向迄今的暗物质的未知属性。
An acceleration scale of order $10^{-10}\mathrm{m/s^2}$ is implicit in the baryonic Tully-Fisher and baryonic Faber-Jackson relations, independently of any theoretical preference or bias. We show that the existence of this scale in the baryonic Faber-Jackson relation is most apparent when data from pressure supported systems of vastly different scales including globular clusters, elliptical galaxies, and galaxy clusters are analyzed together. This suggests the relevance of the acceleration scale $10^{-10}\mathrm{m/s^2}$ to structure formation processes at many different length scales and could be pointing to a heretofore unknown property of dark matter.
