According to general relativity, astrophysical black holes are described by a small number of parameters.Apart from the mass of the black hole ( M ), among the most interesting characteristics is the spin ( a ), which determines the degree of rotation, i.e., the angular momentum of the black hole.The latter is observationally constrained by the spe
