论文摘要
银河系上的冷暗物质中的插入可能会导致苛性环增强。可以在银河旋转曲线中搜索它们为特征。先前的研究表明，具有通用的这些苛性环的证据，这对于不同的星系，参数是常见的。在这里，我们通过改进的统计方法通过一组独立的旋转曲线集检验了这一假设。在新分析中没有发现通用苛性环的证据。
Infall of cold dark matter on a galaxy may result in caustic rings where the particle density is enhanced. They may be searched for as features in the galactic rotation curves. Previous studies suggested the evidence for these caustic rings with universal, that is common for different galaxies, parameters. Here we test this hypothesis with a large independent set of rotation curves by means of an improved statistical method. No evidence for universal caustic rings is found in the new analysis.
