The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

A number of very different approaches to quantum gravity contain a common thread, a hint
that spacetime at very short distances becomes effectively two dimensional. I review this …

We introduce an extension of the Standard Model and General Relativity built upon the
principle of local conformal invariance, which represents a generalization of a previous work …

We study quantum gravity signatures emerging from phenomenologically motivated
multiscale models, spectral actions, and causal set theory within the detector approach to …

If gravity is asymptotically safe, operators will exhibit anomalous scaling at the ultraviolet
fixed point in a way that makes the theory effectively two-dimensional. A number of …

We review the approach to the Standard Model of particle interactions based on spectral
noncommutative geometry. The paper is (nearly) self-contained and presents both the …

In this paper, we discuss two features of the noncommutative geometry and spectral action
approach to the Standard Model: the fact that the model is inherently Euclidean, and that it …

We review the noncommutative approach to the standard model. We start with the
introduction if the mathematical concepts necessary for the definition of noncommutative …

We consider aspects of the noncommutative approach to the standard model based on the
spectral action principle. We show that as a consequence of the incorporation of the Clifford …

I will briefly discuss three cosmological models built upon three distinct quantum gravity
proposals. I will first highlight the cosmological rôle of a vector field in the framework of a …
