Exact black hole solutions in scalar-tensor theories
Nicolas Lecoeur
General Relativity allows for a unique black hole solution, characterized by its mass M, angular momentum J, and electric charge Q. Black holes in General Relativity are thus said…

Rotating black holes embedded in a cosmological background for scalar-tensor theories
Eugeny Babichev, Christos Charmousis, Nicolas Lecoeur
We present solutions of DHOST theories describing a rotating black hole embedded in an expanding universe. The solution is constructed by conformal transformation of a stealth Kerr…

Conformally coupled scalar in Lovelock theory
Eugeny Babichev, Christos Charmousis, Mokhtar Hassaine +1
In arbitrary higher dimension, we consider the combination of Lovelock gravity alongside a scalar-tensor action built out of higher order operators and Euler densities. The latter…
