Gravitational lensing by a charged spherically symmetric black hole immersed in thin dark matter
Xiao-Jun Gao, Xiao-kun Yan, Yihao Yin +1
We investigate the gravitational lensing effect around a spherically symmetric black hole, whose metric is obtained from the Einstein field equation with electric charge and perfec…

Investigating strong gravitational lensing with black hole metrics modified with an additional term
Xiao-Jun Gao, Ji-Ming Chen, Hongsheng Zhang +2
Gravitational lensing is one of the most impressive celestial phenomena, which has interesting behaviors in its strong field limit. Near such limit, Bozza finds that the deflection…
