We review the topic of 4D Einstein–Gauss–Bonnet (4DEGB) gravity, which has been the
subject of considerable interest over the past two years. Our review begins with a general …

We construct a charged rotating black hole in 4D Einstein–Gauss–Bonnet (EGB) gravity
starting from charged black hole in 4D EGB gravity using complex coordinate …

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 …

Shadows and gravitational weak lensing by the Schwarzschild black hole in the string cloud
background with quintessential field - IOPscience This site uses cookies. By continuing to use …

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 …

We have explored the effect of both uniform and nonuniform distributed plasma medium on
gravitational lensing around static black hole in the presence of perfect fluid dark matter …

In this paper, we study the influence of the axion-plasmon, as proposed in [Phys. Rev. Lett.
120, 181803 (2018) PRLTAO 0031-9007 10.1103/PhysRevLett. 120.181803] on the optical …

In this paper, we have studied the particle dynamics, gravitational lensing and energy
processes around the black hole (BH) in Kalb–Ramond (KR) gravity. The motion of particles …

We analysed the shadow cast by charged rotating black hole (BH) in presence of perfect
fluid dark matter (PFDM). We studied the null geodesic equations and obtained the shadow …

This work mainly focuses to unveil the optical features of a black hole. For this objective, we
utilize the metric-affine black hole geometry, including dilation, spin, and shear charge. The …
