论文摘要
如果PBH质量在当前不受限制的“ Sublunar”质量范围内，则原始黑洞（PBH）是暗物质的可行候选者。我们重新审视了PBHS在通货膨胀期间通过虚假真空气泡成核产生的可能性。我们表明，这种情况可以产生同时解释所有暗物质的PBHS人群，解释了Subaru Hyper Suprime-Cam（HSC）数据中的候选事件，并包含Ligo所观察到的沉重的黑洞，也包含了非常重的Supermassive Black Holes的种子。我们通过数值研究证明，如果未来对HSC以及其他光学调查（例如LSST）的观察结果，如果它是暗物质的主要来源，则可以为这种通用PBH形成机制提供确定的测试。
Primordial black holes (PBHs) are a viable candidate for dark matter if the PBH masses are in the currently unconstrained "sublunar" mass range. We revisit the possibility that PBHs were produced by nucleation of false vacuum bubbles during inflation. We show that this scenario can produce a population of PBHs that simultaneously accounts for all dark matter, explains the candidate event in Subaru Hyper Suprime-Cam (HSC) data, and contains both heavy black holes as observed by LIGO and very heavy seeds of supermassive black holes. We demonstrate with numerical studies that future observations of HSC, as well as other optical surveys, such as LSST, will be able to provide a definitive test for this generic PBH formation mechanism if it is the dominant source of dark matter.
