大多数关于活动星系核（包括类星体）的理论讨论都将它们的能量产生归因于黑洞的吸积或其前身阶段例如一个致密的星星团或一个超大质量恒星其最终必然是一个大质量黑洞。我们在这里探讨的可能性，一些活跃的核可能包含两个大质量的黑洞在轨道上彼此。这一假设对观测到的从这些物体中出现的射电喷流的弯曲2和视岁差3提出了新的解释，而且确实可以通过探测轨道运动的直接后果加以验证。
Most theoretical discussions of active galactic nuclei (including quasars) attribute their energy production either to an accreting black hole or to a precursor stage—for instance a dense star cluster or a supermassive star—whose inevitable end point is a massive black hole1. We explore here the possibility that some active nuclei may contain two massive black holes in orbit about each other. This hypothesis suggests a new interpretation for the observed bending2and apparent precession3of radio jets emerging from these objects and may indeed be verified through detection of the direct consequences of orbital motion.
