  This work is devoted to investigate some consequences of black holes physics
beyond the domain of general relativity, mainly in effective extra dimensional
models. The investigation is carried along three gravitational effects, namely
the Hawking radiation, the strong deflection of gravitational lensing and the
formation of quantum black holes. A cosmological thick brane solution is also
investigated. Effective theories and models provide a prominent approach for
testing the limits of known theories and show what would be expected beyond
that. Based on such idea we have used effective models for finding deviations
of general relativity associated to each of the mentioned phenomena.
