The superradiant instability of Kerr-AdS black holes is studied by numerically solving the full 3+1 dimensional Einstein equations. We find that the superradiant instability results in a two stage process with distinct initial and secondary instabilities. At the end of the secondary instability the geometry oscillates at several distinct fundamental frequencies — a multi-oscillating black hole. The multi-oscillating black hole is remarkably close to a black resonator, albeit with a bit of… Expand

TLDR
It is shown that (i) the process stops before all the charge is extracted from the BH, and (ii) the system settles down into a hairy BH: a charged horizon in equilibrium with a scalar field condensate, whose phase is oscillating at the final) critical frequency. Expand

TLDR
It is found that the superradiant instability of a massive boson around a spinning black hole can efficiently convert a significant fraction of a black hole's rotational energy into gravitational radiation. Expand
