论文摘要
许多宇宙学现象导致早期宇宙中原始黑洞的产生。这些现象通常会创造出具有扩展质量和自旋分布的黑洞人群。随着这些黑洞通过鹰式辐射蒸发，它们可以修改各种宇宙学可观察物，导致暗物质的产生，修改有效的相对论自由度的数量，$ n _ {\ rm eff} $，来源，来源是随机的重力波背景并改变了baryeogenesease的动力学。我们认为原始黑洞的鹰蒸发在早期宇宙中具有非平凡的质量和自旋分布。我们证明，这种分布的形状可以强烈影响上述大多数宇宙学观察力。我们概述了我们用来执行此任务的数值机械。我们还发布了一种新版本的Frisbhee，该版本在整个宇宙历史上处理了具有任意质量和自旋分布的原始黑洞的蒸发。
Many cosmological phenomena lead to the production of primordial black holes in the early Universe. These phenomena often create a population of black holes with extended mass and spin distributions. As these black holes evaporate via Hawking radiation, they can modify various cosmological observables, lead to the production of dark matter, modify the number of effective relativistic degrees of freedom, $N_{\rm eff}$, source a stochastic gravitational wave background and alter the dynamics of baryogenesis. We consider the Hawking evaporation of primordial black holes that feature non-trivial mass and spin distributions in the early Universe. We demonstrate that the shape of such a distribution can strongly affect most of the aforementioned cosmological observables. We outline the numerical machinery we use to undertake this task. We also release a new version of FRISBHEE that handles the evaporation of primordial black holes with an arbitrary mass and spin distribution throughout cosmic history.
