Asymptotic Safety implies that observables including scattering amplitudes remain finite at
the highest energy scales. Traditionally, this feature is connected to an interacting fixed point …

Starting from an effective action for quantum gravity, we calculate the quantum gravitational
corrections to the Wald entropy of a four dimensional non-extremal Reissner–Nordström …

A bstract We employ the curvature expansion of the quantum effective action for gravity-
matter systems to construct graviton-mediated scattering amplitudes for non-minimally …

We provide a systematic and updated discussion of a research line carried out by our group
over the last few years, in which gravity is modified at cosmological distances by the …

We present a comprehensive and updated comparison with cosmological observations of
two non-local modifications of gravity previously introduced by our group, the so called RR …

We review past and present results on the non-local form-factors of the effective action of
semiclassical gravity in two and four dimensions computed by means of a covariant …

We investigate the compatibility of cosmological constraints on inflation and the
cosmological constant with the asymptotic safety scenario of quantum gravity. The effective …

We construct the covariant effective field theory of gravity as an expansion in inverse powers
of the Planck mass, identifying the leading and next-to-leading quantum corrections. We …

We show how to reliably calculate quantum gravitational corrections to cosmological models
using the unique effective action formalism for quantum gravity. Our calculations are model …

We consider quantum-gravitational corrections to the Oppenheimer-Snyder metric
describing time-dependent dust ball collapse. The interior metric also describes Friedmann …
