There is a growing interest in investigating homogeneous but anisotropic spacetimes owing to their relation with nonrotating, uncharged black hole interiors. In this context, we present a description of axial perturbations in Kantowski-Sachs spacetimes with a massless scalar field. We truncate the action at the quadratic perturbative order. Perturbations are expressed in terms of perturbative...
The life of a black hole is dominated by dissipative effects, hard to model exactly. I discuss their effects on the full life of a blackhole and its while hole remnant.
Understanding the properties of remnants resulting from the exhaustion of black holes can open new frontiers for quantum gravity phenomenology, both in terms of direct and indirect detection. In my talk, I examine different possible ways in which black hole remnants may manifest their self in the early universe. I discuss possible constraints as well as possible desirable effects in relation...
In this talk we will discuss the quantization of a charged black hole within the improved dynamics of loop quantum gravity and several properties of its semiclassical effective geometries. Adopting a redefined scalar constraint, that renders the algebra of constraints into a Lie algebra, we apply loop quantum gravity techniques adhered to a novel improved dynamics scheme. The model is...
