双黑洞对电磁场的影响

Binary black holes' effects on electromagnetic fields

Carlos Palenzuela, Matthew Anderson, Luis Lehner, Steven L. Liebling, David Neilsen

摘要:

除了产生引力波(GW),双黑洞系统的动力学可以通过影响其附近的等离子体和电磁场的行为来诱导电磁辐射(EM)的发射。我们在这里研究电磁场是如何通过合并的一对轨道黑洞的影响。特别是,我们展示了如何二进制的动态诱导可能的电磁感应发射的变化,以及在后期合并和合并时期的电磁场的可能增强。这些随时间变化的特征可能会在产生可探测辐射的过程中留下印记,并可用于探测引力波的电磁对应物。

英文摘要:

In addition to producing gravitational waves (GW), the dynamics of a binary black hole system could induce emission of electromagnetic (EM) radiation by affecting the behavior of plasmas and electromagnetic fields in their vicinity. We here study how the electromagnetic fields are affected by a pair of orbiting black holes through the merger. In particular, we show how the binary's dynamics induce a variability in possible electromagnetically induced emissions as well as a possible enhancement of electromagnetic fields during the late-merge and merger epochs. These time dependent features will likely leave their imprint in processes generating detectable emissions and can be exploited in the detection of electromagnetic counterparts of gravitational waves.
