Testing Charged Black Holes Embedded in Anisotropic Matter and Surrounded by Plasma through Gravitational Lensing: Bounds from the Sloan Lens ACS Survey
Ritesh Pandey, Shubham Kala, Amare Abebe +2
We investigate weak gravitational lensing by a charged black hole surrounded by anisotropic matter, described by the two-component Kiselev metric, and immersed in a homogeneous pla…
Onset of Chaos and Orbital Instabilities around Rotating Weyl Black Holes
Shubham Kala, M. Yousaf, Pradeep Singh +3
We investigate nonlinear photon motion in the vicinity of a rotating black hole (BH) within Weyl conformal gravity (WCG) by employing Poincare sections, Lyapunov exponents, Fast Ly…
Strong Gravitational Lensing by Lorentzian-Euclidean Black Hole

We investigate the properties of black hole shadows in the renormalization group (RG) improved Bonanno-Reuter spacetime, incorporating quantum gravitational corrections via the sca…
Thermodynamics and Optical Properties of Charged Black Holes in Bumblebee gravity Sourced by a Cloud of Strings
Faizuddin Ahmed, Shubham Kala, Ahmad Al-Badawi
In theories where the Lorentz symmetry of gravity is spontaneously broken, a non-minimally coupled bumblebee vector field acquires a nonzero vacuum expectation value, leading to mo…
