New Entropy formulae from Grey Galaxies and Revolving black holes in AdS

We investigate new black hole solutions in AdS space that dominate the ensemble at high angular momentum. We conjecture that these black holes are the endpoint of the super radiant instability of Kerr AdS black holes. We also argue that these black holes provide a new 5 parameter set of supersymmetric black holes in AdS_5 \times S^5.
