Abstract

We present the images of binary black holes (BHs) using the Majumdar–Papapetrou multi-BH solution, depending on the parameters of the problem: the BH masses, the distance between them, and the inclination of the observer. The images consist of shadows and photon rings. We find that a photon ring structure appears between the BHs. The trajectories of photons are calculated.

双黑洞的阴影和光子环

摘要我们根据问题的参数：双黑洞的质量、它们之间的距离以及观测者的倾角，利用马朱姆达尔-帕佩特罗多黑洞解法展示了双黑洞（BHs）的图像。图像由阴影和光子环组成。我们发现在 BH 之间出现了光子环结构。我们计算了光子的轨迹。

期刊介绍： Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoplesâ€™ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
