WebThis paper deals with formulation of analytic solution for greybody factor taking a rotating black hole (BH) in the vicinity of perfect fluid dark matter. To this end, the Klein–Gordon equation is transformed into the standard Schrödinger equation in order to portray the behavior of effective potential. We compute the asymptotic solutions in ... WebFeb 10, 2024 · We provide semi-analytic bounds on the greybody factors and study the sparsity of Hawking radiation of mass-less uncharged scalar fields. Our results show that the scalar and electric charges contribute oppositely to the greybody factor and the sparsity of the Hawking radiation cascade.
