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.…

Ephemeral Oscillons in Scalar-Tensor Theories: The Higgs-like case
Matteo Piani, Javier Rubio, Francisco Torrenti
We investigate the post-inflationary evolution of a non-minimally coupled inflaton field in scalar-tensor theories, framed within the flexible framework of Einstein-Cartan gravity.…

Preheating in Einstein-Cartan Higgs Inflation: Oscillon formation
Matteo Piani, Javier Rubio
We make use of classical lattice simulations in 3 + 1 dimensions to study the preheating stage of Higgs Inflation in Einstein-Cartan gravity. Focusing for concreteness on a simplif…
