引力替代理论中黑洞的Blandford-Znajek机制

Blandford-Znajek mechanism in black holes in alternative theories of gravity

Guancheng Pei, Sourabh Nampalliwar, Cosimo Bambi, Matthew J. Middleton

摘要:

根据Blandford-Znajek机制,黑洞喷流是由致密物体的旋转能量驱动的。在这项工作中,我们考虑的可能性,黑洞周围的度量可能无法描述的克尔解决方案,我们研究如何改变Blandford-Znajek模型。如果Blandford-Znajek机制是形成喷流的原因,那么对喷流功率的估计结合另一种测量可以测试黑洞候选者的性质,并限制可能偏离克尔解的情况。然而,只有当有可能获得比今天更精确的测量时,这种方法才可能与其他技术竞争。

英文摘要:

According to the Blandford-Znajek mechanism, black hole jets are powered by the rotational energy of the compact object. In this work, we consider the possibility that the metric around black holes may not be described by the Kerr solution and we study how this changes the Blandford-Znajek model. If the Blandford-Znajek mechanism is responsible for the formation of jets, the estimate of the jet power in combination with another measurement can test the nature of black hole candidates and constrain possible deviations from the Kerr solution. However, this approach might become competitive with respect to other techniques only when it will be possible to have measurements much more precise than those available today.
