具有非常规渐近行为的旋转黑洞周围的光子轨迹

Trajectories of photons around a rotating black hole with unusual asymptotics

Yong-Zhuang Li, Xiao-Mei Kuang

AI总结:

本文研究了EMD理论中具有非常规渐近行为的旋转黑洞周围的光子轨迹,揭示了非常规渐近行为对光子轨迹的显著影响,为黑洞阴影和成像研究提供了新见解。

摘要:

大多数黑洞解的特征是渐近平坦或渐近(反)德西特行为,但一些具有非常规渐近行为的黑洞也已被构造出来,这被认为能为我们理解引力的本质提供重要洞见。本文聚焦于Einstein-Maxwell-dilaton (EMD)理论中一个具有非常规渐近行为的旋转黑洞,创新性地分析了该黑洞背景周围的光子轨迹,表明非常规渐近行为对光子轨迹有显著影响。我们期望我们的分析能为黑洞阴影和成像的研究提供更多见解。

英文摘要:

Most black hole solutions are characterized with asymptotically flat, or asymptotically (anti) de-Sitter behaviors, but some black holes with unusual asymptotics have also been constructed, which is believed to provide remarkable insights into our understanding of the nature of gravity. In this paper, focusing on a rotating black hole with unusual asymptotics in Einstein-Maxwell-dilaton (EMD) theory, we innovatively analyze the photons' trajectories around this black hole background, showing that the unusual asymptotics has significant influences on the photons' trajectories. We expect that our analysis could give more insights in the scenario of black holes' shadow and image.
