论文摘要
局部保形对称性引入了将其分为（重力 - ）电和磁性（张量）部分的保形曲率（Weyl张量）。从重力电场中预期牛顿潮汐力，而一般偏见的框架拖拉效应从引力磁场出现。可以通过其特征向量和特征值来可视化对称，无纹状体引力和引力量张量场。在本文中，我们描绘了一个缓慢旋转的黑洞周围的重力和引力磁场。这表明在活动星系中心观察到的超快速流出的现象可能为旋转超质量黑洞的引力磁场提供证据。我们还质疑当代观察中的当前问题是否可以通过在扰动的FLRW模型中大规模上包含引力磁性来解决。
Local conformal symmetry introduces the conformal curvature (Weyl tensor) that gets split into its (gravito-) electric and magnetic (tensor) parts. Newtonian tidal forces are expected from the gravitoelectric field, whereas general-relativistic frame-dragging effects emerge from the gravitomagnetic field. The symmetric, traceless gravitoelectric and gravitomagnetic tensor fields can be visualized by their eigenvectors and eigenvalues. In this essay, we depict the gravitoelectric and gravitomagnetic fields around a slowly rotating black hole. This suggests that the phenomenon of ultra-fast outflows observed at the centers of active galaxies may give evidence for the gravitomagnetic fields of spinning supermassive black holes. We also question whether the current issues in our contemporary observations might be resolved by the inclusion of gravitomagnetism on large scales in a perturbed FLRW model.
