Abstract

We investigate the implications of memory burden on the gravitational wave (GW) spectrum arising from the Hawking evaporation of light primordial black holes (PBHs). By considering both rotating (Kerr) and non-rotating (Schwarzschild) PBHs, we demonstrate that the overproduction of primordial GWs from burdened PBHs could impose stringent constraints on the parameters governing backreaction effects. These constraints, derived from ΔNeff measurements by Planck and prospective experiments such as CMB-S4 and CMB-HD, offer novel insights into the impact of memory burden on PBH dynamics.

用引力波制约有负担的 PBHs

我们研究了记忆负担对轻原始黑洞（PBHs）霍金蒸发产生的引力波（GW）频谱的影响。通过考虑旋转（克尔）和非旋转（施瓦兹柴尔德）PBHs，我们证明了有记忆负担的PBHs过量产生原始引力波会对支配反作用效应的参数造成严格的约束。这些约束条件来自普朗克的ΔNeff测量以及CMB-S4和CMB-HD等前瞻性实验，为我们提供了关于记忆负担对PBH动力学影响的新见解。

期刊介绍： Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
