Organisé par : Institut Henri Poincaré

In this talk, I will present an Ernst-like formulation for stationary axisymmetric solutions in Einstein-Maxwell-Scalar Field gravity. The main idea is to encode the gravitational, electromagnetic, and scalar degrees of freedom into a set of potentials, extending the standard Ernst formalism beyond the vacuum and Einstein-Maxwell sectors. I will first explain how this framework reproduces several
