论文摘要
显示了对棕褐色世界内产生的潮汐电荷的约束。为了描述事件地平线望远镜合作最近宣布的M87*参数,使用旋转黑洞的阴影,与报道的阴影的循环相比,偏离了所报道的阴影的偏差,从而产生了大量非局部效应的上限,该效应被认为是由五二维凸起的四维式阐述中的潮汐电荷。因此,偏离圆形$ \ Lessim 10 \%$的偏差导致潮汐电荷上的上限$ \ sillesim 0.004m^2 $。
A constraint on the tidal charge generated within a brane world is shown. Using the shadow of a rotating black hole in a brane context in order to describe the M87* parameters recently announced by the Event Horizon Telescope Collaboration, the deviation from circularity of the reported shadow produces an upper bound on the bulk's nonlocal effect, which is conceived of as a tidal charge in the four-dimensional brane induced by the five-dimensional bulk. Therefore, a deviation from circularity $\lesssim 10\%$ leads to an upper bound on the tidal charge $\lesssim 0.004M^2$.
