Black holes with gauge fields

"Building on deliverable 5, analytic methods will be combined with numerical tools to study black-hole solutions with vector or ""gauge"" fields. Time evolutions of single-black-hole solutions obtained from the Einstein equations coupled to the Maxwell equations will be analysed and the results compared with approximation calculations. The stability of the spacetimes will be explored through studying different types of initial perturbations superposed onto the initial black-hole solution. The emission of gravitational and scalar radiation will be computed."
