The Ayón-Beato–García model is the first exact charged regular black hole with a source. The model was proposed by Eloy Ayón Beato and Alberto García in 1998 based on the minimal coupling between a nonlinear electrodynamics model and general relativity, considering a static and spherically symmetric spacetime. Later the same authors reinterpreted the first non-singular black hole geometry, the Bardeen toy Model, as a nonlinear-electrodynamics-based regular black hole. Nowadays, it is known that the Ayón-Beato–García model may mimic the absorption properties of the Reissner–Nordström metric, from the perspective of the absorption of massless test scalar fields.
