Determination of the metric of a Schwarzschild black hole surrounded by a halo of dark matter

Abstract Following the landmark acquisition of the first image of a black hole, systems comprising a black hole enveloped by a dark matter halo have attracted considerable attention. This work implements a novel method to analyze the structure of a system composed of a Schwarzsch...

Exact rotating dilatonic branch in ModMax electrodynamics without Maxwell analogue

Abstract We present a novel class of rotating dilatonic solutions within the framework of Einstein–ModMax-type gravity. The configuration belongs to the nonlinear sector characterized by $$\mathcal F/\mathcal G=\textrm{const}$$ F / G = const and carries nontrivial electric and ma...
