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 g_el=2.
