In a recent remarkable work just published in Physical Review Letters as an Editor's suggestion, William East and Frans Pretorius (E&P) studied the non-linear growth of the superradiant instability. And the endpoint matches hairy black holes discovered by the Gr@v team. Read here a viewpoint article by Sam Dolan.
Carolina Benone successfully defended her PhD thesis "Scalar fields in black hole spacetimes and analogues". The exam took place in U. Federal do Pará, in Belém, Brazil, on July 14th 2017. The thesis was supervised by Luis Crispino (UFPa) and Gr@v member C. Herdeiro. Congratulations Carolina!
Here, the numerical data described in Fig. 4 of the paper "Kerr black holes with synchronised hair: an analytic model and dynamical formation", arXiv:1706.06597, together with an explanatory pdf file and two Mathematica notebooks, is made available for public use.
The data consists of four solutions of Kerr black holes with scalar hair and six solutions of Kerr black holes with Proca hair. These families of solutions were first presented in the papers:
Abstract: We study wormhole solutions obtained via applying dualities and complexifications to the vacuum Weyl metrics generated by massive rods and by point masses. The most interesting finding are wormholes with locally flat geometry supported by rings of negative energy.
