Dressing a black hole with a time-dependent Galileon
Eugeny Babichev, Christos Charmousis
We present a class of exact scalar-tensor black holes for a shift-symmetric part of the Horndeski action. The action includes a higher order scalar tensor interaction term. We find…
Integrability in conformally coupled gravity: Taub-NUT spacetimes and rotating black holes
Yannis Bardoux, Marco M. Caldarelli, Christos Charmousis
We consider four dimensional stationary and axially symmetric spacetimes for conformally coupled scalar-tensor theories. We show that, in analogy to the Lewis-Papapetrou problem in…
AdS black holes with arbitrary scalar coupling
Marco M. Caldarelli, Christos Charmousis, Mokhtar Hassaïne
A general class of axionic and electrically charged black holes for a self-interacting scalar field nonminimally coupled to Einstein gravity with a negative cosmological constant i…
