论文摘要
在温暖的暗物质方案中，新闻技术形式主义仅适用于大于“速度分散截止”的星系质量。在这项工作中，我们将预测扩展到低于速度色散截止的质量，从而解决了“缺失的卫星问题”，以及不超过测得的恢复光学深度所需的其余框架超紫色亮度临界值。我们发现这两种现象的预测与观察之间的共识。作为副产品，我们从第一原则获得了经验的Tully-Fisher关系。
In the warm dark matter scenario, the Press-Schechter formalism is valid only for galaxy masses greater than the "velocity dispersion cut-off". In this work we extend the predictions to masses below the velocity dispersion cut-off, and thereby address the "Missing Satellites Problem", and the rest-frame ultra-violet luminosity cut-off required to not exceed the measured reionization optical depth. We find agreement between predictions and observations of these two phenomena. As a by-product, we obtain the empirical Tully-Fisher relation from first principles.
