Black Holes in the Asymptotic Safety Program

The Asymptotic Safety scenario in quantum gravity provides a powerful framework to investigate the properties of black holes and spacetime singularities near the Planck scale. A rather robust prediction of this approach is that the final state of the black hole evaporation process is a Planck size remnant. Moreover, if the black hole is formed during a realistic gravitational collapse, quantum gravitational effects tend to suppress the inflation of the mass function at the Cauchy horizon. The scalar singularity in the future evolution of the spacetime is still present although its strength is much weaker than the classical case.
