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…
GRFolres: A code for modified gravity simulations in strong gravity
Llibert Aresté Saló, Sam E. Brady, Katy Clough +6
GRFolres is an open-source code for performing simulations in modified theories of gravity, based on the publicly available 3+1D numerical relativity code GRChombo. Note: Submitted…
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…
Distinctive Features of Hairy Black Holes in Teleparallel Gauss-Bonnet Gravity
Sebastian Bahamonde, Daniela D. Doneva, Ludovic Ducobu +2
We examine the teleparallel formulation of non-minimally coupled scalar Einstein-Gauss-Bonnet gravity. In the teleparallel formulation, gravity is described by torsion instead of c…
Neutron stars in Gauss-Bonnet gravity -- nonlinear scalarization and gravitational phase transitions
Daniela D. Doneva, Christian J. Krüger, Kalin V. Staykov +1
It was recently discovered that scalarized neutron stars in scalar-tensor theories can undergo a gravitational phase transition to a non-scalarized (GR) state. Surprisingly, even t…
Differentially rotating scalarized neutron stars with realistic post-merger profile
Kalin V. Staykov, Daniela D. Doneva, Lavinia Heisenberg +2
The merger remnant of a binary neutron star coalescence is initially strongly differentially rotating. Some properties of these remnants can be accurately modeled through building…
