论文摘要
我们讨论了通过几种不同机制来源的黑洞系统可以成为暗物质通量的来源的可能性。我们首先讨论了两种类型的系统：活跃银河核（AGN）中超质量黑洞周围的冠状热等离子体，以及恒星X射线黑洞二进制（BHB）的增生磁盘。我们探讨了这些黑洞系统如何产生KEV光线暗物质通量，并发现这些来源的深色通量可能太弱，无法说明当前的Xenon1t过量。另一方面，黑洞可能是促进并增强沉重的暗物质颗粒的好加速器。如果考虑碰撞或深色电磁作用，那么这些颗粒就可以逃脱并达到检测器的基准速度0.1C。我们还将黑洞质量区域扩展到原始黑洞（PBH），并讨论通过PBHS的超级促进kev浅色深色通量的可能性。
We discuss the possibility that accreting black hole systems can be sources for dark matter flux through several different mechanisms. We firstly discuss two types of systems: coronal thermal plasmas around supermassive black holes in active galactic nuclei (AGNs), and accretion disks of stellar-mass X-ray black hole binaries (BHBs). We explore how these black hole systems may produce keV light dark matter fluxes and find that the dark fluxes from those sources might be too weak to account for the current XENON1T excess. On the other hand, black holes can be good accelerators to accrete and boost heavy dark matter particles. If considering collisions or dark electromagnetism, those particles can then escape and reach the benchmark speed of 0.1c at the detector. We also extend the black hole mass region to primordial black holes (PBHs) and discuss the possibility of contributing to keV light dark flux via superradiance of PBHs.
