Universal AdS Black Holes in Theories with 16 Supercharges and Their Microstates

We provide a universal microscopic counting for the microstates of the asymptotically AdS black holes and black strings that arise as solutions of the half-maximal gauged supergravity in 4 and 5 dimensions. These solutions can be embedded in all M-theory and type II string backgrounds with an AdS vacuum and 16 supercharges and provide an infinite set of examples dual to N = 2 and N = 4 conformal field theories in four and three dimensions, respectively. The counting is universal and it is performed by either studying the large N limit of the relevant supersymmetric index of the dual field theory or by using the charged Cardy formula.

Automated summary

The study provides a universal counting for the microstates of asymptotically AdS black holes and black strings in 4 and 5 dimensions, which can be embedded in various M-theory and type II string backgrounds. These solutions are dual to N = 2 and N = 4 conformal field theories and the counting is performed through either studying the large N limit of the relevant supersymmetric index or using the charged Cardy formula.
