Non-linear Structure Formation in Planck+DESI Favoured Interacting Dark Energy Cosmologies
Yuejia Zhai, Carsten van de Bruck, Eleonora Di Valentino +2
Following our previous work constraining interacting dark energy (IDE) models, which showed their potential to alleviate the Hubble tension, in this work we investigate the non-lin…

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.…

A low-redshift preference for an interacting dark energy model
Yuejia Zhai, Marco de Cesare, Carsten van de Bruck +2
We explore an interacting dark sector model in trace-free Einstein gravity where dark energy has a constant equation of state, , and the energy-momentum transfer potential is…
