3+1 non-linear evolution of Ricci-coupled scalar-Gauss-Bonnet gravity
Daniela D. Doneva, Llibert Aresté Saló, Stoytcho S. Yazadjiev
Scalar-Gauss-Bonnet (sGB) gravity with an additional coupling between the scalar field and the Ricci scalar exhibits very interesting properties related to black hole stability, ev…
Shadows of rotating hairy Kerr black holes coupled to time periodic scalar fields with non-flat target space
Galin N. Gyulchev, Ayush Roy, Lucas G. Collodel +3
We study the shadows cast by rotating hairy black holes with two non-trivial time-periodic scalar fields having a non-flat Gaussian curvature of the target space spanned by the sca…
Black hole no-hair theorem for self-gravitating time-dependent spherically symmetric multiple scalar fields
Stoytcho Yazadjiev, Daniela Doneva
We prove under certain weak assumptions a black hole no-hair theorem in spherically symmetric spacetimes for self-gravitating time-dependent multiple scalar fields with an arbitrar…
Effects of mass and self-interaction on nonlinear scalarization of scalar-Gauss-Bonnet black holes
Alexandre M. Pombo, Daniela D. Doneva
It was recently found that in certain flavours of scalar-Gauss-Bonnet gravity linearly stable bald black holes can co-exist with stable scalarized solutions. The transition between…
Testing the limits of scalar-Gauss-Bonnet gravity through nonlinear evolutions of spin-induced scalarization
Daniela D. Doneva, Llibert Aresté Saló, Katy Clough +2
Quadratic theories of gravity with second order equations of motion provide an interesting model for testing deviations from general relativity in the strong gravity regime. Howeve…
Dynamical Scalarization during Neutron Star Mergers in scalar-Gauss-Bonnet Theory
Hao-Jui Kuan, Alan Tsz-Lok Lam, Daniela D. Doneva +3
In certain classes of the scalar-Gauss-Bonnet theory strong spacetime curvature in the vicinity of neutron stars and black holes can spontaneously trigger scalarization in the comp…
