Structure of Kerr black hole spacetimes in Weyl conformal gravity (2507.01379v1)
Published 2 Jul 2025 in gr-qc and hep-th
Abstract: We analyze the stationary, uncharged, rotating, vacuum solution to Weyl conformal gravity. We elucidate the causal and ergoregion structure of the spacetimes found in the parameter space of the metric for positive mass. These are then compared to the corollary Kerr, Kerr-de Sitter, and Kerr-Anti-de Sitter solutions to general relativity. Additionally, we investigate and derive the extremal limits for both the horizons and ergosurfaces of the spacetimes.
