Absorption and scattering of massless scalar waves by black holes in quasi-topological gravity
Abstract We consider massless scalar field perturbations of regular black holes in quasi-topological gravity. After reviewing various regular black hole solutions, we compute the total absorption cross-section and the partial absorption cross-section for different choices of the parameters using the...
