带电黑洞准圆螺旋与并合的广义相对论模拟:GW150914及其基本物理意义

General relativistic simulations of the quasi-circular inspiral and merger of charged black holes: GW150914 and fundamental physics implications

Gabriele Bozzola, Vasileios Paschalidis

摘要:

我们进行广义相对论模拟的带电黑洞目标GW 150914。我们发现,inspiral是最有效的检测黑洞电荷通过引力波和GW 150914是兼容的电荷质量比高达0.3。我们的工作适用于电荷和磁荷,以及具有U(1)(隐藏或暗)电荷的黑洞理论。利用我们的结果,我们放置一个上限偏离广义相对论的动力学,强场制度的所谓理论的修改重力(MOG)。

英文摘要:

We perform general-relativistic simulations of charged black holes targeting GW150914. We show that the inspiral is most efficient for detecting black hole charge through gravitational waves and that GW150914 is compatible with having charge-to-mass ratio as high as 0.3. Our work applies to electric and magnetic charge, and to theories with black holes endowed with U(1) (hidden or dark) charges. Using our results we place an upper bound on the deviation from general relativity in the dynamical, strong-field regime of the so-called theory of MOdified Gravity (MOG).
