Dynamical theory for spherical black holes in modified gravity
Asier Alonso-Bardaji, David Brizuela
We provide a general algorithm to construct a Hamiltonian, such that its dynamical flow covariantly defines any given spherically symmetric and static metric. This Hamiltonian is d…
Gravitational wave propagation in bigravity in the late universe
David Brizuela, Marco de Cesare, Araceli Soler Oficial
We carry out a detailed analytical investigation of the propagation of gravitational waves in ghost-free bimetric gravity in a late-time de Sitter epoch. In this regime, the dynami…
Radiative properties of a nonsingular black hole: Hawking radiation and gray-body factor
Asier Alonso-Bardaji, David Brizuela, Marc Schneider
We study the radiative properties of a spherical and singularity-free black-hole geometry recently proposed in the literature. Contrary to the Schwarzschild spacetime, this geometr…
Dipolar perturbations of nonbidiagonal black holes in bigravity
David Brizuela, Marco de Cesare, Araceli Soler Oficial
In bimetric gravity, nonbidiagonal solutions describing a static, spherically symmetric, and asymptotically flat black hole are given by a pair of Schwarzschild geometries, one in…
