论文摘要
我们表明，Kerr黑洞（BH）与周围磁场的引力磁相互作用会引起电场，该电场将带电的颗粒加速到BH附近的超相关能量。沿着BH旋转轴，这些电子/质子可以达到甚至数千个PEV的能量，因此在长γ-射线爆发中（GRB）中的出色质量BH（grbs）和活性银河核（AGN）中的超大质量BHS可以有助于Ultraigh-rytraigh-energy-energy-energy-energy-Energy宇宙rays（UHECR）（UHECRS）。在离轴纬度上，颗粒在GEV能量处加速至数百GEV的能量并发出同步辐射。此过程发生在BH旋转轴周围的$ 60^\ circ $之内，并且由于赤道对称性，它形成了双锥发射。我们概述了描述这些加速度和辐射过程的理论框架，它们如何提取Kerr BH的旋转能以及GRB天体物理学的后果。
We show that the gravitomagnetic interaction of a Kerr black hole (BH) with a surrounding magnetic field induces an electric field that accelerates charged particles to ultra-relativistic energies in the vicinity of the BH. Along the BH rotation axis, these electrons/protons can reach energies of even thousands of PeV, so stellar-mass BHs in long gamma-ray bursts (GRBs) and supermassive BHs in active galactic nuclei (AGN) can contribute to the ultrahigh-energy cosmic rays (UHECRs) thorough this mechanism. At off-axis latitudes, the particles accelerate to energies of hundreds of GeV and emit synchrotron radiation at GeV energies. This process occurs within $60^\circ$ around the BH rotation axis, and due to the equatorial-symmetry, it forms a double-cone emission. We outline the theoretical framework describing these acceleration and radiation processes, how they extract the rotational energy of the Kerr BH and the consequences for the astrophysics of GRBs.
