Left panel: relative differential EBL energy density deficit as a function of distance along the line of sight for various EBL photon energy densities in the case of an R = 50 h⁻¹ Mpc void located at z_v = 0.5. The red vertical lines indicate the boundaries of the void. Right panel: angle dependence (θ is the angle with respect to the direct line of sight through the center of the void) of the EBL energy density in the presence of an R = 50 h⁻¹ Mpc at the z_v = 0.5 void (dashed lines), compared to the homogeneous case (which does not have any angle dependence; solid lines), at a representative near-UV photon energy of ϵ = 8 eV for three positions (redshifts) along the line of sight: at the center of the void (black, lower curves), within the void but behind its center (red curves), and behind the void (blue and cyan, upper curves).
