Linear stability of nonbidiagonal black holes in massive gravity
Eugeny Babichev, Richard Brito, Paolo Pani
We consider generic linear perturbations of a nonbidiagonal class of static black-hole solutions in massive (bi)gravity. We show that the quasinormal spectrum of these solutions co…
Beyond Fab Four
E. Babichev, C. Charmousis, D. Langlois +1
We show that the two additional Lagrangians that appear in theories beyond Horndeski can be reexpressed in terms of simple generalizations of the "John" and "Paul" terms of the Fab…
Charged Galileon black holes
Eugeny Babichev, Christos Charmousis, Mokhtar Hassaine
We consider an Abelian gauge field coupled to a particular truncation of Horndeski theory. The Galileon field has translation symmetry and couples non minimally both to the metric…
Black holes in massive gravity
Eugeny Babichev, Richard Brito
We review the black hole solutions of the ghost-free massive gravity theory and its bimetric extension and outline the main results on the stability of these solutions against smal…
