Rapidly rotating Myers-Perry-AdS black holes are unstable against rotational superradiance. From the onset of the instability, cohomogeneity-1 black resonators are constructed in five-dimensional asymptotically AdS space. By using the cohomogeneity-1 metric, perturbations of the cohomogeneity-1 black resonators are also studied.

The author reports on the new phase which Myers-Perry black holes evolve into after the superradiant instability renders them unstable. This new phase are cohomogeneity-1 black resonators and photonic black resonators. Perturbations are computed around these solutions and their instabilities are analyzed.
The subject is technically very challenging. However, the author managed to write a clear instructive text, pick out the relevant equations, and references the relevant literature where appropriate, making the manuscript an informative read.
This manuscript adequately covers the author's contribution to the 4th International Conference on Holography,String Theory and Discrete ApproachHanoi, Vietnam, 2020.
