论文摘要
大多数旋转支持的星系严格遵循将圆速度与重子含量联系起来的Baryonic Tully-Fisher关系（BFTR）。目前，这种坚定的经验关系被认为起源于修饰的重力或暗物质光环效应。在这项工作中，我们构建了基于物理的BFTR版本，该版本建立在已知的缩放关系，磁盘动力学（加速度，混蛋和SNAP）上，该版本也揭示了负责这种现象学的基础元素。我们采用银河系作为典范，将两种主要理论与此改进版本进行定量比较。此外，还提供了BFTR的无量纲变体，该变体可以允许其用作分析工具来帮助理解银河动力学。
Most rotationally-supported galaxies strictly follow the Baryonic Tully-Fisher Relation (BFTR) linking circular velocity with baryon content. This firmly established empirical relationship is currently thought to have origins in either modified gravity or dark matter halo effects. In this work, we construct a physically-based version of the BFTR founded on known scaling relations, disk dynamics (acceleration, jerk and snap) that also reveals the foundational elements responsible for this phenomenology. We employ the Milky Way galaxy as an exemplar to quantitatively compare the two leading theories against this improved version. Additionally, a dimensionless variant of the BFTR is also provided which may permit its use as an analytic tool to aid in the understanding of galactic dynamics.
