宇宙早期形成的原始黑洞(PBH)构成了一个吸引人的暗物质候选者。在星际介质的气体环境中，带有吸积盘的PBH自然会发出风和喷流等流出。我们首次讨论了具有显著自旋的PBH如何维持强大的相对论喷流并产生相关的茧。喷流和风可以有效地储存它们的动能，并通过激波加热周围的气体。聚焦于LEO T矮星系，我们证明了这些效应形成了新的测试，并在一个重要的∼10−2M⊙−106m⊙质量范围内设置了新的PBH限制，包括与LIGO和室女座合作观测到的引力波相关的参数空间。观测辐射的形态将允许区分喷流和风的贡献，因此建立了一种识别旋转的多溴联苯的新方法。
Primordial black holes (PBHs) formed in the early Universe constitute an attractive candidate for dark matter. Within the gaseous environment of the interstellar medium, PBHs with accretion disks naturally launch outflows such as winds and jets. We discuss for the first time how PBHs with significant spin can sustain powerful relativistic jets and generate associated cocoons. Jets and winds can efficiently deposit their kinetic energies and heat the surrounding gas through shocks. Focusing on the Leo T dwarf galaxy, we demonstrate that these effects form novel tests and set new limits on PBHs over a significant ∼10−2M⊙ − 106M⊙ mass range, including the parameter space associated with gravitational wave observations by the LIGO and VIRGO Collaborations. Observing the morphology of emission will allow to distinguish between jet and wind contributions, and hence establishes a new method for identifying spinning PBHs.
