Optical Features of AdS Black Holes in the Novel 4D Einstein-Gauss-Bonnet Gravity Coupled to Nonlinear Electrodynamics

An alternative theory of gravity that has attracted much attention recently is the novel four-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity. The rescaled by Gauss-Bonnet (GB) coupling constant $\alpha \rightarrow \alpha/(D - 4)$ in $ D dimensions and redefined as limit $D 4$. Thus, this manner, GB term yields a non-trivial contribution to gravitational dynamics. In fact, regularized black hole solutions applications 4D EGB have also been extensively explored. work, motivated recent astrophysical observations, we present an in-depth study optical features AdS holes coupled exponential nonlinear electrodynamics (NED), such shadow geometrical shape, energy emission rate, deflection angle quasinormal modes. Taking into account these dynamic quantities, investigate effects on solution varying parameters models. More specifically, show variation NED parameters, cosmological constant, imprints specific signatures electrodynamics, thus leading possibility directly testing models using observations.
