银河系中原初黑洞的可探测性

On the detectability of primordial black holes in the Galaxy

Julia K. Becker, Marek A. Abramowicz, Peter L. Biermann

摘要:

在1e15 g到1e26 g的质量范围内,原始黑洞(PBH)作为暗物质的可能贡献仍然未被探索。在这方面的贡献,我们调查的可能性PBH与银河系天体相互作用的电磁信号。我们发现,通道的信号不能被观察到,因为,根据质量,无论是相互作用的概率或能量损失太小。此外,我们讨论了质量>1e26 g的高质量多溴联苯的可能影响,其中多溴联苯仍然可以贡献约10%的暗物质。在这里,我们发现,一个显着的一部分PBH可以在哈勃时间被捕获。因此,这些捕获可能导致可检测的影响。

英文摘要:

In the mass range of 1e15 g up to 1e26 g, primordial black holes (PBHs) as a possible contribution to the dark matter are still unexplored. In this contribution, we investigate the possibility of an electromagnetic signal from PBH interactions with astrophysical objects in the Galaxy. We find that a signal from passages cannot be observed, since, depending on the mass, either the interaction probability or the energy loss is too small. Further, we discuss possible effects from high-mass PBHs at masses >1e26 g, where PBHs can still contribute to the dark matter at the order of ~10%. Here, we find that a significant fraction of PBHs can be captured in the Hubble time. These captures could therefore lead to detectable effects.
