Freeze-out and spectral running of primordial gravitational waves in viscous cosmology
Giuseppe Fanizza, Eliseo Pavone, Luigi Tedesco
We investigate the impact of shear viscosity on the propagation of primordial gravitational waves (pGW) after inflation. Without assuming a specific inflationary scenario we focus…
A Light-Cone Approach to Higher-Order Cosmological Observables
Pierre Béchaz, Giuseppe Fanizza, Giovanni Marozzi +1
We develop a second-order cosmological perturbation theory on a background geometry expressed in terms of light-cone coordinates, extending the first-order analyses available in th…
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.…
