压缩Kaluza-Klein黑洞时空中的强引力透镜

Strong gravitational lensing in a squashed Kaluza-Klein black hole spacetime

Yue Liu, Songbai Chen, Jiliang Jing

摘要:

研究了具有压缩视界的Kaluza-Klein黑洞中的强引力透镜.我们发现额外维度印记的大小与光子球的半径、相对论图像的偏转角、角位置和放大率有关。假设银河系中心超大质量天体的引力场可以用这个度规描述,我们估计了强场极限下的引力透镜系数和观测量的数值。

英文摘要:

We investigate the strong gravitational lensing in a Kaluza-Klein black hole with squashed horizons. We find the size of the extra dimension imprints in the radius of the photon sphere, the deflection angle, the angular position and magnification of the relativistic images. Supposing that the gravitational field of the supermassive central object of the Galaxy can be described by this metric, we estimated the numerical values of the coefficients and observables for gravitational lensing in the strong field limit.
