Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

In this study, the gravitational deflection angle of photons in the weak field limit (or the weak
deflection angle) and shadow cast by the electrically charged and spherically symmetric …

Eikonal quasinormal modes (QNMs) of black holes (BHs) and parameters of null geodesics,
ultimately tied to the appearance of BHs to external observers, are known to be related, and …

In this study of Kerr-type black hole within the Starobinsky–Bel–Robinson gravity, we unveil
intriguing dynamics. We observe that the black hole spin weakens the effective potential …

In this work we investigate a Schwarzschild-type black hole that is corrected by the
Generalised Uncertainty Principle (GUP) and possesses topological defects within the …

The current manuscript deals with the tidal force effects, geodesic deviation, and shadow
constraints of the Schwarzschild-like black hole theorised in Starobinsky–Bel-Robinson …

In this study, the optical properties of a renormalization group improved (RGI) Schwarzschild
black hole (BH) are investigated in a plasma medium. Beginning with the equations of …

The effect of spacetime curvature on optical properties may provide an opportunity to
suggest new tests for gravity theories. In this paper, we investigated gravitational weak …

This study investigates the optical properties of a rotating black hole in Starobinsky-Bel-
Robinson gravity, characterized by the additional parameter β. The black hole is assumed to …

In this work, we have studied weak gravitational lensing effect around black hole and
determine shadow radius in GUP-corrected-Schwarzschild spacetime (S-GUP) in presence …
