Resilience and implications of adiabatic CMB cooling
Ruchika, William Giarè, Elsa M. Teixeira +1
We investigate potential deviations from the standard adiabatic evolution of the cosmic microwave background (CMB) temperature, , using the latest Sunyaev-Zeldovich…
A frequentist view on the two-body decaying dark matter model
Thomas Montandon, Elsa M. Teixeira, Adèle Poudou +1
Decaying dark matter (DDM) has emerged as an interesting framework to extend the -cold-dark-matter (LCDM) model, as many particle physics models predict that dark matter may not…
Implications of distance duality violation for the tension and evolving dark energy
Elsa M. Teixeira, William Giarè, Natalie B. Hogg +3
We investigate whether a violation of the distance duality relation (DDR), , connecting the angular diameter and luminosity distances, can explain the Hubb…
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.…
Self-interacting neutrinos in light of recent CMB and LSS data
Adèle Poudou, Théo Simon, Thomas Montandon +2
We update constraints on a simple model of self-interacting neutrinos involving a heavy scalar mediator with universal flavor coupling. According to past literature, such a model i…
Deciphering Coupled Scalar Dark Sectors
Saba Rahimy, Elsa M. Teixeira, Ivonne Zavala
Coupled dark sector models have gained significant attention, motivated by recent advances in cosmology and the pressing need to address unresolved puzzles. In this work, we study…
