Rotating Black Holes with Monopole Hair — •Jutta Kunz1, Burkhard Kleihaus1, and Francisco Navarro-Lerida2 — 1University of Oldenburg — 2Universidad Complutense de Madrid
We study rotating black holes in Einstein-Yang-Mills-Higgs theory. These black holes emerge from static black holes with monopole hair when a finite horizon angular velocity is imposed. At critical values of the horizon angular velocity and the horizon radius, they bifurcate with embedded Kerr-Newman black holes. The non-Abelian black holes possess an electric dipole moment, but no electric charge is induced by the rotation. We deduce that gravitating regular monopoles possess a gyroelectric ratio gel=2.
