We study the physical properties of four-dimensional, string-theoretical, horizonless “fuzzball” geometries by imaging their shadows. Their microstructure traps light rays straying near the would-be horizon on long-lived, highly redshifted chaotic orbits. In fuzzballs sufficiently near the scaling limit this creates a shadow much like that of a black hole, while avoiding the paradoxes associated with an event horizon. Observations of the shadow size and residual glow can potentially discriminate between fuzzballs away from the scaling limit and alternative models of black compact objects.

Fuzzball Shadows:来自微观结构的新兴视野

我们通过对它们的阴影进行成像来研究四维、弦理论、无视界“模糊球”几何的物理特性。它们的微观结构在长期存在的、高度红移的混沌轨道上捕获在潜在地平线附近杂散的光线。在足够接近缩放限制的模糊球中,这会产生一个很像黑洞的阴影,同时避免与事件视界相关的悖论。对阴影大小和残余辉光的观察可能会区分远离缩放限制的模糊球和黑色致密物体的替代模型。
