Strong field gravitational lensing of particles by a black-bounce-Schwarzschild black hole
Guansheng He, Jiaxu Huang, Zhongwen Feng +2
The gravitational lensing of relativistic and nonrelativistic neutral massive particles in the black-bounce-Schwarzschild black hole spacetime is investigated in the strong deflect…

Thermodynamics of the arbitrary dimensional FRW universe: Joule-Thomson expansion
Haximjan Abdusattar, Shi-Bei Kong, Minawar Omar +1
In this paper, we investigate the thermodynamics especially the Joule-Thomson expansion of the -dimensional FRW (Friedmann-Robertson-Walker) universe with a perfect fluid. We de…
