# Quasinormal modes of black holes in a toy-model for cumulative quantum gravity

## TL;DR

This paper investigates how quantum gravity effects could influence black hole quasinormal modes and assesses their potential detectability through gravitational wave observations.

## Contribution

It introduces a model for quantum metric corrections and analyzes their impact on black hole quasinormal modes.

## Key findings

- Quantum corrections alter quasinormal mode frequencies.
- Potential observability of quantum effects with gravitational wave detectors.
- Model provides a framework for testing quantum gravity signatures.

## Abstract

The idea that quantum gravity effects might leak outside the horizon of a black hole has recently been intensively considered. In this study, we calculate the quasinormal modes as a function of the location and amplitude of a generic metric perturbation distorting to the Schwarzschild spacetime. We conclude on the possible observability of quantum metric corrections by current and future gravitational wave experiments.
