Plasma impact on black hole shadows and gravitational weak lensing in the Einstein-Maxwell-scalar theory
《Communications in Theoretical Physics》2025年第1期130-142,共13页Mirzabek Alloqulov Sanjar Shaymatov Abdul Jawad Oripjon Zaripov 
supported by the National Natural Science Foundation of China under Grant No.11675143;the National Key Research and Development Program of China under Grant No.2020YFC2201503。
In this paper,we investigate the optical properties of a non-rotating charged black hole(BH)in the Einstein-Maxwell-scalar(EMS)theory,together with a plasma medium.We first consider the photon sphere and shadow radius...

Particle dynamics,black hole shadow and weak gravitational lensing in the f(Q)theory of gravity
《Communications in Theoretical Physics》2023年第12期115-128,共14页Allah Ditta Xia Tiecheng Farruh Atamurotov Ibrar Hussain G Mustafa 
funded by the National Natural Science Foundation of China 11975145;partly supported by Research Grant FZ-20200929344 and F-FA2021-510 of the Uzbekistan Ministry for Innovative Development;Grant No.ZC304022919 to support his Postdoctoral Fellowship at Zhejiang Normal University
We study the particle dynamics around a black hole(BH)in f(Q)gravity.First,we investigate the influence of the parameters of f(Q)gravity on the horizon structure of the BH,photon orbits and the radius of the innermost...
