Probing Cosmic Expansion and Early Universe with Einstein Telescope
Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52
Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…
Quantum gravitational corrections at third-order curvature, acoustic analog black holes and their quasinormal modes
R. Casadio, C. Noberto Souza, R. da Rocha
Quasinormal modes for bosonic (scalar, electromagnetic, and axial gravitational) and fermionic field perturbations, radiated from black holes that carry quantum gravitational corre…
Quantum maximally symmetric space-times
Pedro Meert, Andrea Giusti, Roberto Casadio
We show that 4-dimensional maximally symmetric spacetimes can be obtained from a coherent state quantisation of gravity, always resulting in geometries that approach the Minkowski…
Quasinormal modes for coherent quantum black holes
Tommaso Antonelli, Andrea Giusti, Roberto Casadio +1
Coherent quantum black holes are quantum geometries obtained by means of a mean-field-like approach to the gravitational interaction. This procedure attenuates the classical spacet…
Quantum Gravitational Hair in Gravastars and Observational Tests
Italo Perrucci, Folkert Kuipers, Roberto Casadio
Using the effective field theory of quantum gravity at second order in curvature, we calculate quantum corrections to the metric of gravastars and the closely related dark energy s…
