Overview

Analysis shows that nonlinear charge and exotic matter affect photon dynamics in AdS black holes, indicating significant modifications to spacetime.

Key Points

  • Photon trajectories reveal that optical properties are influenced by parameters like nonlinear charge and quintessence, leading to unique shadow characteristics.
  • The calculated photon sphere radii vary from 6.12 to 19.30 depending on the quintessence normalization, showcasing diverse spacetime effects.
  • Using Lagrangian formalism, we analyze null geodesics to uncover critical insights into the effective potential and orbital stability of test particles around the black hole.
  • Periastron precession shows dependencies on exotic matter parameters, allowing for measurable deviations from predictions made by standard general relativity.
