Abstract
It is an intuitive but general conviction that black holes (BHs) result in highly excited states representing both the hydrogen atom and the quasi-thermal emission in quantum gravity. Here we show that such an intuitive picture is more than a picture, discussing a model of quantum BH somewhat similar to the historical semi-classical model of the structure of a hydrogen atom introduced by Bohr in 1913. Our model has important implications for the BH information paradox and is in perfect agreement with existing results in the literature, starting from the famous result of Bekenstein on the area quantization.
