利用阴影约束膜黑洞的潮汐荷

Constraining the tidal charge of brane black holes using their shadows

Juliano C. S. Neves

摘要:

一个约束的膜世界内产生的潮汐电荷。利用膜背景下的旋转黑洞的阴影来描述最近由事件视界望远镜协作组公布的M87* 参数,所报道的阴影的圆度偏差产生了体积非局域效应的上界,它被认为是由五维体积引起的四维膜中的潮汐荷.因此,偏离圆度$\lesssim 10\%$导致潮汐电荷$\lesssim 0.004M^2$的上限。

英文摘要:

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 $\lesssim 0.004M^2$.
