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 …

Mass inflation is a well established instability, conventionally associated to Cauchy horizons
(which are also inner trapping horizons) of stationary geometries, leading to a divergent …

We review the question of whether the fundamental laws of nature limit our ability to probe
arbitrarily short distances. First, we examine what insights can be gained from thought …

We find accurate quasinormal frequencies of a quantum corrected black hole constructed in
the renormalization group theory via the coordinate-independent iterative procedure …

We investigate the shadow, deflection angle, and the greybody bounding of a Schwarzschild-
AdS/dS black hole in scale-dependent gravity. We used the EHT data to constrain the …

Asymptotically safe gravity is based on the idea that the main contribution to the
Schwarzschild-like black hole spacetime is due to the value of the gravitational coupling …

We investigate the compatibility of minimally coupled scalar, fermion and gauge fields with
asymptotically safe quantum gravity, using nonperturbative functional renormalization group …

We develop an effective framework for the μ¯ scheme of holonomy corrections motivated by
loop quantum gravity for vacuum spherically symmetric space-times. This is done by …
