The Goldstone Awakens: Unimodular dark energy in scale-invariant gravity
Mariaveronica De Angelis, Javier Rubio
We construct an cosmology based on scale invariance and unimodular gravity in which the Goldstone boson of dilatations establishes a predictive connection between inflation a…

The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…

Tracing cosmic stretch marks: probing scale invariance in the early Universe
Mariaveronica De Angelis, Chiara Cecchini, Massimiliano Rinaldi
This paper investigates a scale-invariant inflationary model characterized by a scalar field non-minimally coupled to gravity and a curvature term quadratic in the Ricci scalar. Th…
