论文摘要
我们提出了一个精确的五维（$ 5D $）旋转的常规黑洞公制，带有偏差参数$ k \ geq 0 $，在$ 5D $ kerr黑洞（$ k = 0 $）和$ 5D $ kerr-newman（$ r \ r \ r \ gg k $）之间进行了插值。这个$ 5D $旋转的常规黑洞是一般相对论与非线性电动力学的精确解决方案。有趣的是，对于给定的参数$ k $的给定值，它退出了一个关键的角动量$ a = a_e $，对应于带有简并视野的极端旋转的常规黑洞，而对于$ a <a_e $，一个人具有非外部旋转的常规黑洞，外部和内部视野。由于校正因子（$ e^{ - k/r^2} $），这是由量子参数激发的，因此修改了巨孔和黑洞阴影。
We present an exact five-dimensional ($5D$) rotating regular black hole metric, with a deviation parameter $k\geq 0$, that interpolates between the $5D$ Kerr black hole ($k=0$) and $5D$ Kerr-Newman ($r \gg k$). This $5D$ rotating regular black hole is an exact solution of general relativity coupled to nonlinear electrodynamics. Interestingly, for a given value of parameter $k$ there exits a critical angular momentum $a=a_E$ which corresponds to extremal rotating regular black hole with degenerate horizons, while for $a<a_E$, one has non-extremal rotating regular black hole with outer and inner horizons. Owing to the correction factor ($e^{-k/r^2}$), which is motivated by the quantum arguments, the ergoregion and black hole shadow are modified.
