Spin-induced scalarized black holes in Phys. Rev. Lett.

Can a black hole be different from the Kerr paradigm depending on its spin? In paper to publishd in Physical Review Letters, Gr@v members C. Herdeiro and E. Radu, in collaboration with H. Silva and N. Yunes (U. Illinois at Urbana-Champaigne, US) and T. Sotirou (U. Nottingham, UK), show that the phenomenon of spontaneous scalarisation can lead to non-Kerr black holes, only if they spin fast enough.
