论文摘要
随着许多进步的推动，电磁观测站现在已经达到了超大质量黑洞的地平线。地平线在我们宇宙中的存在和特性是现在可以解决的杰出基本问题之一。在这里，我们研究了区分黑洞和紧凑型物体的能力，重点是紧凑物体周围的热点镜头。我们特别与玻色子和Proca星作为中心对象一起工作，并表明缺乏地平线会产生一个特征 - 光子通过中心对象耕作并产生额外的图像。此功能应该是通用的，对于弱耦合到标准模型的物质制成的中心对象。
Pushed by a number of advances, electromagnetic observatories have now reached the horizon scale of supermassive black holes. The existence and properties of horizons in our universe is one of the outstanding fundamental issues that can now be addressed. Here we investigate the ability to discriminate between black holes and compact, horizonless objects, focusing on the lensing of hot spots around compact objects. We work in particular with boson and Proca stars as central objects, and show that the absence of a horizon gives rise to a characteristic feature -- photons that plough through the central object and produce an extra image. This feature should be universal for central objects made of matter weakly coupled to the standard model.
