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.…

Screening Mechanisms on White Dwarfs: Symmetron & Dilaton
Joan Bachs-Esteban, IlÃdio Lopes, Javier Rubio
This work provides the first comparison of the symmetron and dilaton fields in white dwarfs. We show how these screening mechanisms behave inside {such stars} and their impact on s…

Structural Implications of the Chameleon Mechanism on White Dwarfs
Joan Bachs-Esteban, IlÃdio Lopes, Javier Rubio
We study the impact of the chameleon mechanism on the structure of white dwarfs. Using a shooting method of our design, we solve the corresponding scalar-tensor equilibrium equatio…
