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 …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

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 …

New physics beyond the Standard Model can give rise to stochastic gravitational-wave
backgrounds, for example, through cosmic strings. In this way, gravitational-wave searches …

We study the asymptotic safety conjecture for quantum gravity in the presence of matter
fields. A general line of reasoning is put forward explaining why gravitons dominate the high …

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 discover that asymptotically safe quantum gravity could predict the top-quark mass. For a
broad range of microscopic gravitational couplings, quantum gravity could provide an …
