Query: Double-extended Kerr-Schild form for $5D$ electrovacuum solutions   Five-dimensional Einstein-Maxwell-Chern-Simons equations are investigated in
the framework of an extended Kerr-Schild strategy to search for black holes
solutions. The fulfillment of Einstein equations constrains the Chern-Simons
coupling constant to a value determined by the trace of the energy-momentum
tensor of the electromagnetic configuration.
