We apply Sen's entropy formalism to the study of the near horizon geometryand the entropy of asymptotically AdS black holes in gauged supergravities. Inparticular, we consider non-supersymmetric electrically charged black holeswith AdS_2 xS^{d-2} horizons in U(1)^4 and U(1)^3 gauged supergravities in d=4and d=5 dimensions, respectively. We study several cases includingstatic/rotating, BPS and non-BPS black holes in Einstein as well as inGauss-Bonnet gravity. In all examples, the near horizon geometry and black holeentropy are derived by extremizing the entropy function and are given entirelyin terms of the gauge coupling, the electric charges and the angular momentumof the black hole.Comment: 27 pages, no figures, references adde
