Absorption and Scattering Cross Section of Regular Black Holes

Figure 5

The behavior of the partial scattering cross sections 𝜎_sca, from 𝑙=1 to 𝑙=6, at 𝑀𝜔=1 for the scalar wave is scattered from the regular black hole with 𝛼=0.4. The width of the main scattering angle becomes narrower and the differential scattering cross section becomes higher as partial wave number 𝑙 increases.
