Gravity model. given by higher-order scal.r curvature corrections are bel.eved to bear important consequences. Einstein-Bel.Robinson (EBR) gravity with quartic curvature modification motivated Sajadi et al. to expl.re static spherical.y symmetric bl.ck hol. sol.tions using perturbative methods. In this study, inspired by their work, we investigate AdS bl.ck hol. shadows in EBR gravity and demonstrate how the gravity parameter al.ers the energy emission rate. Final.y, we address the same probl.m in the presence of pl.sma, because the bl.ck hol.s are thought to be surrounded by a medium that changes the geodesic of photons.
