Null geodesics around a black hole with weakly coupled global monopole charge
Mohsen Fathi, J. R. Villanueva, Thiago R. P. Caramês +1
In this paper, we study an asymptotically flat black hole spacetime with weakly nonminimally coupled monopole charge. We analytically and numerically investigate light ray propagat…

Black hole in a generalized Chaplygin-Jacobi dark fluid: shadow and light deflection angle
Mohsen Fathi, J. R. Villanueva, Gilberto Aguilar-Pérez +1
We investigate a generalized Chaplygin-like gas with an anisotropic equation of state, characterizing a dark fluid within which a static spherically symmetric black hole is assumed…
