论文摘要
在这项工作中，我们得出了作用在穿过超轻（标量场）暗物质的黑洞上的动态摩擦的简单封闭式表达式，涵盖了非相对论和相对论的黑洞速度。我们的派生基于黑洞空位中备有已知的散射幅度，它包括黑洞自旋的效果，并且可以很容易地扩展到矢量和张量光场。我们的结果涵盖了最新的数值和以前的非相关性治疗，对超轻暗物质中的动态摩擦治疗。
In this work we derive simple closed-form expressions for the dynamical friction acting on black holes moving through ultralight (scalar field) dark matter, covering both non-relativistic and relativistic black hole speeds. Our derivation is based on long known scattering amplitudes in black hole spacetimes, it includes the effect of black hole spin and can be easily extended to vector and tensor light fields. Our results cover and complement recent numerical and previous non-relativistic treatments of dynamical friction in ultralight dark matter.
