论文摘要

磁性电荷的黑洞(MBHS)是标准模型和一般相对论的有趣解决方案。 They may possess a "hairy" electroweak-symmetric corona outside the event horizon, which speeds up their Hawking radiation and leads them to become nearly extremal on short timescales.他们的群众可以从普朗克秤到地球质量。我们研究了各种方法来搜索原始产生的MBH,并估计其丰度的上限。 We revisit the Parker bound on magnetic monopoles and show that it can be extended by several orders of magnitude using the large-scale coherent magnetic fields in Andromeda.这设定了与质量无关的约束,即MBH的丰富度小于$ 6 \ times 10^{ - 3} $乘以暗物质的$。 MBH也可以在天体物理系统(例如太阳,地球或中子之星)中捕获。在那里,它们可以通过与带电的MBH合并或吸收核子合并而成为非敌人。所得的鹰辐射可以被检测为中微子,光子或热。 High-energy neutrino searches in particular can set a stronger bound than the Parker bound for some MBH masses, down to an abundance $10^{-7}$ of dark matter.

Magnetically charged black holes (MBHs) are interesting solutions of the Standard Model and general relativity. They may possess a "hairy" electroweak-symmetric corona outside the event horizon, which speeds up their Hawking radiation and leads them to become nearly extremal on short timescales. Their masses could range from the Planck scale up to the Earth mass. We study various methods to search for primordially produced MBHs and estimate the upper limits on their abundance. We revisit the Parker bound on magnetic monopoles and show that it can be extended by several orders of magnitude using the large-scale coherent magnetic fields in Andromeda. This sets a mass-independent constraint that MBHs have an abundance less than $6 \times 10^{-3}$ times that of dark matter. MBHs can also be captured in astrophysical systems like the Sun, the Earth, or neutron stars. There, they can become non-extremal either from merging with an oppositely charged MBH or absorbing nucleons. The resulting Hawking radiation can be detected as neutrinos, photons, or heat. High-energy neutrino searches in particular can set a stronger bound than the Parker bound for some MBH masses, down to an abundance $10^{-7}$ of dark matter.
