Loopy Black-Hole Remnants
Asier Alonso-Bardaji
The quantized area predicted by loop quantum gravity suggests the existence of a lower bound for black-hole horizons. We prove this intuition within a covariant effective model for…
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…
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…
Formation of nonsingular spherical black holes with holonomy corrections
Asier Alonso-Bardaji
We present a canonical model of spherical gravity with covariant corrections motivated by loop quantum gravity. The effective Hamiltonian defines univocally a family of geometries…
