The renormalization group plays an essential role in many areas of physics, both
conceptually and as a practical tool to determine the long-distance low-energy properties of …

Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field
theories, in particular for quantum gravity. Significant progress on this program has led to a …

Asymptotic safety generalizes asymptotic freedom and could contribute to understanding
physics beyond the Standard Model. It is a candidate scenario to provide an ultraviolet …

In this contribution, we discuss the asymptotic safety scenario for quantum gravity with a
functional renormalization group approach that disentangles dynamical metric fluctuations …

The asymptotic-safety paradigm posits that the symmetry of quantum theories of gravity and
matter is enhanced to quantum scale symmetry, ie, scale symmetry in the presence of …

We study fixed points of quantum gravity with renormalization group methods and a
procedure to remove convergence-limiting poles from the flow. The setup is tested within the …

We reconstruct the Lorentzian graviton propagator in asymptotically safe quantum gravity
from Euclidean data. The reconstruction is applied to both the dynamical fluctuation graviton …

Over the last years the asymptotic safety program has matured into a serious candidate for a
quantum theory of gravity compatible with observations. The rapid technical progress in …

We investigate the asymptotic safety conjecture for quantum gravity including curvature
invariants beyond Ricci scalars. Our strategy is put to work for families of gravitational …

We set out to bridge the gap between regular black-hole spacetimes and observations of a
black-hole shadow by the Event Horizon Telescope. We explore modifications of spinning …
