论文摘要

在多维潜力中,在通货膨胀期间通过量子隧穿成核的原始气泡可能使目前可检测到一些遗物。在辐射时代,这些气泡变成了黑洞,这可能解释了Ligo黑洞,超大型黑洞,并且可能在暗物质中起重要作用。通常,这些黑洞被以球形波数据包向外传播的形式的能量不足所包围。在这项工作中,我们研究了这种宇宙等离子体的扰动如何在重组之前消散,从而导致CMB的光谱扭曲。我们发现,在最后一个散射表面上可能存在一些稀有区域,其中包含巨大的黑洞,这些区域产生了$ $ $ type畸变的可能检测到的点状信号。

Primordial bubbles that possibly nucleate through quantum tunneling during inflation in a multidimensional potential might have left some relic detectable at the present time. These bubbles turn into black holes during the radiation era, which may account for the LIGO black holes, supermassive black holes, and may play an important role in dark matter. Typically, these black holes are surrounded by an energy deficit in the form of a spherical sound wave packet propagating outwards. In this work we study how this perturbation of the cosmic plasma dissipates before the time of recombination, leading to spectral distortions in CMB. We find that there may exist some rare regions on the last scattering surface containing huge black holes, which have produced potentially detectable point-like signals of $μ$-type distortions.
