| contents | 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 spacetime singularities of general relativity by replacing them with integrable singularities in the quantum-corrected geometry. After discussing some relevant observables for a novel geometry for spherically symmetric black holes, we investigate the quasinormal modes spectrum of scalar, electromagnetic, and gravitational fields for the proposed model. The results indicate potential deviations from general relativity, the magnitude of which is gauged by the value of the ultraviolet regulator of the model (physically identifiable as a matter core). Observations of the ringdown phase in black hole mergers could help detect such deviations. |
