摘要:

Blandford-Znajek 机制是 Penrose 过程的电磁体现,目前是解释黑洞发射相对论性喷流的最佳理论候选者。在本次演讲中,我们对 Blandford-Znajek 机制及黑洞磁层解析构造提供了现代综述。高阶微扰修正至关重要,以便在黑洞处于高自旋状态时产生与数值模拟互补的结果,并有望预测 Blandford-Znajek 理论非微扰结构的新特征。此外,我们通过具体例子表明,这些微扰修正以非简并方式依赖于所考虑的底层引力理论,从而能够将 BZ 功率作为强引力特征,在未来视界尺度观测中检验广义相对论及其他引力理论。

英文摘要:

The Blandford-Znajek mechanism is an electromagnetic manifestation of the Penrose process that currently constitutes the best theoretical candidate to explain the launching of relativistic jets by black holes. In this talk we offer a modern review about the Blandford-Znajek mechanism and the analytic construction of black hole magnetospheres. Higher order perturbative corrections are crucial in order to produce results that are complementary to numerical simulations when the black hole is in the high-spin regime, and can potentially predict new features about the non-perturbative structure of the Blandford-Znajek theory. Moreover, we show by means of an explicit example that these perturbative corrections depend in a non-degenerate manner on the underlying theory of gravity considered, enabling one to use the BZ power emitted as a strong-gravity signature to test General Relativity against alternative theories of gravity on future horizon-scale observations.
