强引力波中的扩展黑洞

Extended black holes in strong gravitational waves

Li-Ming Cao, Oleg Evnin, Nobuyoshi Ohta

摘要:

我们描述了一个大类的解决方案,在纯引力,引力和超引力对应的扩展高维黑洞与强(非线性)引力波沿其世界体积传播。对于纯引力,扩展的黑洞是四维空间中的点状史瓦西黑洞的高维类似物。对于超引力,它们是非极值p-膜。引力波既可以充满空间,也可以局限于扩展黑洞的世界体积周围。我们给出的解包含了大量描述不同非线性引力波模振幅的光锥时间的任意函数。

英文摘要:

We describe a large class of solutions in pure gravity, dilaton gravity and supergravity corresponding to extended higher-dimensional black holes with strong (non-linear) gravitational waves propagating along their worldvolume. For pure gravity, the extended black holes are higher-dimensional analogs of the point-like Schwarzschild black hole in four dimensions. For supergravity, they are non-extremal p-branes. The gravitational waves can be both space-filling and localized around the worldvolume of the extended black holes. The solutions we present contain a large number of arbitrary functions of the light-cone time describing the amplitudes of different non-linear gravitational wave modes.
