快速旋转的黑洞内的马洛夫-奥利奇点

The Marolf-Ori singularity inside fast spinning black holes

Lior M. Burko, Gaurav Khanna

摘要:

本文用数值方法研究了在标量场或真空引力扰动下,线性扰动快速自旋黑洞内视界出射支处的有效激波奇异性。我们证明了Marolf-Ori奇异性的发生,包括标量场模型的标量场$ϕ$中的阶数单位的变化,以及真空引力扰动模型的Weyl标量$ψ_0$和$ψ_4$(由视界函数$Δ$适当地重新缩放)和Kretschmann标量曲率$K$中的阶数单位的变化。我们量化的冲击锐化效应,并表明,在所有情况下,其利率与预期一致。

英文摘要:

The effective shock wave singularity at the outgoing leg of the inner horizon of a linearly perturbed fast spinning black hole is studied numerically for either scalar field, or vacuum, gravitational perturbations. We demonstrate the occurrence of the Marolf-Ori singularity, including changes of order unity in the scalar field $ϕ$ for the scalar field model, and in the Weyl scalars $ψ_0$ and $ψ_4$ (rescaled appropriately by the horizon function $Δ$) and the Kretschmann curvature scalar $K$ for the vacuum, gravitational perturbations model for both null and timelike geodesic observers. We quantify the shock sharpening effect and show that in all cases its rate agrees with expectations.
