Strong gravity beyond General Relativity
Llibert Aresté Saló
This thesis focuses on the application of numerical relativity methods to the solutions of problems in strong gravity. Our goal is the study of mergers of compact objects in the st…
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…
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…
The problem of calculating the -Bogoliubov coefficient in Non-Oscillating models
Jaume de Haro, Llibert Aresté Saló
The calculation of the Bogoliubov coefficients is a key piece to obtain the reheating temperature of the Universe. In all cases this calculation is performed either in toy models w…
Gravitational particle production of superheavy massive particles in Quintessential Inflation II: -attractors
Llibert Aresté Saló, Jaume de Haro
We compute the gravitational production of conformally coupled superheavy particles during the phase transition from the end of inflation to the beginning of kination for -attra…
Cosmological solutions in spatially curved universes with adiabatic particle production
Llibert Aresté Saló, Jaume de Haro
We perform a qualitative and thermodynamic study of two models when one takes into account adiabatic particle production. In the first one, there is a constant particle production…
