Black hole limit
WebApr 11, 2024 · Gravitational lensing by rotating black holes in strong deflection limit has been investigated in Refs. [46, 54, 57, 58, 58, 60, 70]. On this paper, we have concentrated on asymptotically flat, static, and spherically symmetric spacetimes and our results can be extended to the rotating black holes and alternatives. WebThe near-horizon metric(NHM) refers to the near-horizon limit of the global metric of a black hole. NHMs play an important role in studying the geometry and topologyof black holes, but are only well defined for extremalblack holes.
