论文摘要
我们回顾了有关径向加速关系（RAR）及其解释为基本或新兴法律的一些最新结果。前者的解释与一类修改的重力理论一致，这些理论驳回了星系中对暗物质的需求（特别是MOND）。我们的最新分析包括对后者之间的改进和贝叶斯测试的兼容性，证实了基本RAR的假设在用于推断RAR的同一数据中以超过5 $σ$拒绝了基本RAR的假设。
We review some of our recent results about the Radial Acceleration Relation (RAR) and its interpretation as either a fundamental or an emergent law. The former interpretation is in agreement with a class of modified gravity theories that dismiss the need for dark matter in galaxies (MOND in particular). Our most recent analysis, which includes refinements on the priors and the Bayesian test for compatibility between the posteriors, confirms that the hypothesis of a fundamental RAR is rejected at more than 5$σ$ from the very same data that was used to infer the RAR.
